Classicists debate the origin of the name Pleiades. It ostensibly derives from the name of their mother, Pleione, effectively meaning "daughters of Pleione". However, the name of the star- cluster likely came first, and Pleione was invented to explain it.Robin Hard, The Routledge Handbook of Greek Mythology (London: Routledge, 2004), p. 518.

The Milky Way as seen from Price-Whelan 1 The star cluster has larger component 'a' and a smaller component 'b'. The component 'a' was later resolved in two components: an Eastern component 'aE' and a Western component 'aW'. The three components do not only differ in position, but also in stellar content.

Since the black hole at the center of the HCSS is essentially invisible, an HCSS would look very similar to a faint cluster of stars. Determining that an observed star cluster is a HCSS requires measuring the orbital velocities of the stars in the cluster via their Doppler shifts and verifying that they are moving much faster than expected for stars in an ordinary star cluster. This is a challenging observation to make because an HCSS would be relatively faint, requiring many hours of exposure time even on a 10m class telescope. The most promising places to look for HCSSs are cluster of galaxies, for two reasons: first, most of the galaxies in a galaxy cluster are elliptical galaxies which are believed to have formed through mergers.

Hubble. In 2018, research confirmed that the chemical composition of the gas in the Magellanic Stream Leading Arm more closely resembles the composition of the Small Magellanic Cloud, rather than the Large Magellanic Cloud, by looking at light from background quasars shining through the Stream and analysing the spectrum of light that is either absorbed by, or let through it. This analysis confirmed that the gas most likely originated from the Small Magellanic Cloud, thereby indicating that the Large Magellanic Cloud is 'winning' in the gravity tug of both Clouds working on the Magellanic Stream. In 2019 astronomers discovered the young star cluster Price-Whelan 1 using Gaia data. The star cluster has a low metallicity and belongs to the leading arm of the Magellanic Clouds.

NGC 6356 is a globular cluster located in the constellation Ophiuchus. It is designated as II in the galaxy morphological classification scheme and was discovered by the German-born British astronomer William Herschel on 18 June 1784. The star cluster is more dense and bright towards the middle. 6356 is located 80' north east of the brighter NGC 6333.

Many globular clusters, such as the 13-Gyr old cluster M30 (pictured), are mass segregated. In astronomy, dynamical mass segregation is the process by which heavier members of a gravitationally bound system, such as a star cluster or cluster of galaxies, tend to move toward the center, while lighter members tend to move farther away from the center.

The stars of Segue 2 were probably among the first stars to form in the Universe. Currently, there is no star formation in Segue 2. Segue 2 is located near the edge of Sagittarius Stream and at the same distance. It may once have been a satellite of Sagittarius Dwarf Elliptical Galaxy or its star cluster.

There are about 40 member stars within M103, two of which have magnitudes 10.5, and a 10.8 red giant, which is the brightest within the cluster. Observation of M103 is generally dominated by the appearance of Struve 131, though the star is not a member of the 172-star cluster. M103 is about 25 million years old.

The Andromeda Galaxy is known to harbor a dense and compact star cluster at its very center. In a large telescope it creates a visual impression of a star embedded in the more diffuse surrounding bulge. In 1991, the Hubble Space Telescope was used to image Andromeda Galaxy's inner nucleus. The nucleus consists of two concentrations separated by .

This minor planet was named after the nymph Merope from Greek mythology. She is one of the seven Pleiades, daughters of the Titan Atlas and the sea- nymph Pleione (). Merope is also a bright star in the constellation of Taurus and one of the brightest members of the Pleiades star cluster, also known as the "Seven Sister".

HD 180450 is a 6th magnitude star in the constellation Lyra, approximately 1,400 light years away from Earth. It is a red giant star of the spectral type M0III, meaning it has a surface temperature of about 3,500 kelvins. It is much larger and brighter, yet cooler, than our Sun. It is also a star in a star cluster.

Jean L. Turner is an astrophysicist and distinguished professor in the Department of Physics and Astronomy at the University of California, Los Angeles. She was lead author on research and discovery of a particular star cluster in the dwarf galaxy NGC 5253, considered 'remarkable' for being an extremely dusty gas cloud and having highly efficient star formation.

NGC 1755 (also known as ESO 56-SC28) is an open star cluster in the Large Magellanic Cloud in the Dorado constellation, It is about 120 light years across and due to its size could be a globular cluster. It has a diameter of 2.6′ and an apparent magnitude of 9.9. It was discovered by James Dunlop in 1826.

Oxford University Press, December 2014. Web. 20 January 2015. However, in mythology the name was used for the Pleiades, seven divine sisters, the name supposedly deriving from that of their mother Pleione and effectively meaning "daughters of Pleione". In reality, the name of the star cluster almost certainly came first, and Pleione was invented to explain it.

Its shape has been described as "triangular"; this 80-star cluster is unusually large, more than half a degree in diameter, larger than the diameter of the full Moon. Ancient globular cluster NGC 6535. There are several globular clusters in Hydra. M68 (NGC 4590) is a globular cluster visible in binoculars and resolvable in medium amateur telescopes.

M83, also known as the Southern Pinwheel Galaxy, is located on the border of Hydra and Centaurus, M68 is a globular cluster near M83, and M48 is an open star cluster in the western end of the serpent.

Several stars in the Hyades star cluster, including Kappa Tauri, were photographed during the total solar eclipse of May 29, 1919, by the expedition of Arthur Eddington in Príncipe and others in Sobral, Brazil, that confirmed Albert Einstein's prediction of the bending of light around the Sun according to his general theory of relativity which he published in 1915.

16 Comae Berenices is a single star in the northern constellation of Coma Berenices. 16 Comae Berenices is the Flamsteed designation. It is a member of the Coma Star Cluster and is visible to the naked eye with an apparent visual magnitude of 4.96. Based upon an annual parallax shift of , it is located about 279 light years away.

The system is part of star cluster NGC 1981. The binary nature of this system was suggested by A. Blaauw and T. S. van Albada in 1963. It is a double-lined spectroscopic binary with an orbital period of 18.6556 days and an eccentricity of 0.31. The eccentricity is considered unusually large for such a close system.

The Merope Nebula in true colour from an amateur telescope. The Merope Nebula (also known as Tempel's Nebula and NGC 1435) is a diffuse reflection nebula in the Pleiades star cluster, surrounding the 4th magnitude star Merope. It was discovered on October 19, 1859 by the German astronomer Wilhelm Tempel. The discovery was made using a 10.5cm refractor.

One notable member is LOri167, which is a wide binary consisting of a potential planetary- mass object and a brown dwarf. Observations of the star cluster with the Spitzer Space Telescope have shown that 25% of the low-mass stars and 40% of the substellar objects are surrounded by a circumstellar disk. Two of these being actively photoevaporated by Meissa.

NGC 110 is an open star cluster located in the constellation Cassiopeia. It was discovered by the English astronomer John Herschel on October 29, 1831. It is unknown if the members are physically related, or if the cluster exists at all. It is barely visible against the background sky, and the two dozen member stars seem to be at various distances.

The distance, chemical composition, and age of Teide 1 could be established because of its membership in the young Pleiades star cluster. Using the most advanced stellar and substellar evolution models at that moment, the team estimated for Teide 1 a mass of , which is below the stellar-mass limit. The object became a reference in subsequent young brown dwarf related works.

NGC 6401 is a globular cluster in the constellation Ophiuchus. William Herschel discovered this star cluster in 1784 with his 47 cm telescope, but mistakenly believed it to be a bright nebula. Later his son, John Herschel, was to make the same error because the technology of the day was insufficient to allow the individual stars to be resolved visually.

It is now known that Hooke's equipment was far too imprecise to allow the measurement to succeed. Gamma Draconis was the same star James Bradley used in 1725 in discovering the aberration of light. Hooke's activities in astronomy extended beyond the study of stellar distance. His Micrographia contains illustrations of the Pleiades star cluster as well as of lunar craters.

Open star cluster NGC 6823 is about 50 light years across and lies about 6000 light years away. The center of the cluster formed about two million years ago and is dominated in brightness by a host of bright young blue stars. Outer parts of the cluster contain even younger stars. It forms the core of the Vulpecula OB1 stellar association.

Computer simulations have shown that the Pleiades were probably formed from a compact configuration that resembled the Orion Nebula. Astronomers estimate that the cluster will survive for about another 250 million years, after which it will disperse due to gravitational interactions with its galactic neighborhood. Together with the open star cluster of the Hyades the Pleiades form the Golden Gate of the Ecliptic.

A stellar association is a very loose star cluster, whose stars share a common origin, but have become gravitationally unbound and are still moving together through space. Associations are primarily identified by their common movement vectors and ages. Identification by chemical composition is also used to factor in association memberships. Stellar associations were first discovered by the Armenian astronomer Viktor Ambartsumian in 1947.

Ruprecht 147 or NGC 6774 is a dispersed star cluster in the Milky Way galaxy. It is about 1,000 light years away, which is close to Earth in comparison with other such clusters. In late summer, it can be seen with binoculars in the constellation of Sagittarius. The stars, bound by gravity, are about 2.5 to 3.25 billion years old.

This is a demonstration of the message with color added to highlight its separate parts. The binary transmission sent carried no color information. The Arecibo message is a 1974 interstellar radio message carrying basic information about humanity and Earth sent to globular star cluster M13. It was meant as a demonstration of human technological achievement, rather than a real attempt to enter into a conversation with extraterrestrials.

Nonnus, Dionysiaca 9. (trans. Rouse) Another version is that Dionysus was taken to the rain-nymphs of Nysa, who nourished his infancy and childhood, and for their care Zeus rewarded them by placing them as the Hyades among the stars (see Hyades star cluster). In yet another version of the myth, he is raised by his cousin Macris on the island of Euboea.Conner, Nancy.

Messier 80 (also known as M80 or NGC 6093) is a globular cluster in the constellation Scorpius. It was discovered by Charles Messier in 1781. The star cluster is located midway between α Scorpii (Antares) and β Scorpii in a field in the Milky Way that is rich in nebulae. It can be viewed with modest amateur telescopes as a mottled ball of light.

Subsequent studies have confirmed not only at least 15 O-type stars but also 3 luminous blue variable/Wolf-Rayet star candidates. They also have calculated the total mass of the stars associated with the Dragonfish nebula as 105 solar masses, a mass only comparable with that of the super star cluster Westerlund 1, the most massive stellar association and the brightest nebula known in our galaxy.

Betty Crocker released a new variety of Fruit Gushers in early 2020: "Galactic Fruit Gushers". These featured the flavors "Asteroid Apple", "Berry Star Cluster", and a mystery flavor labeled "Unidentified Flavored Object"; the latter was part of a contest where consumers could guess at the unknown flavor and win prizes "like sweatshirts, hats, blankets, pop sockets, and more". Galactic Fruit Gushers were sold through Walmart.com for .

It has an apparent magnitude of 10.3. Within it lies the triple star system HD 5980, each of its members among the most luminous stars known. Open star cluster NGC 299 is located within the Small Magellanic Cloud. The Tucana Dwarf galaxy, which was discovered in 1990, is a dwarf spheroidal galaxy of type dE5 that is an isolated member of the Local Group.

13 Comae Berenices is a probable binary star system in the northern constellation of Coma Berenices. It has an apparent visual magnitude of 5.17, which is bright enough to be faintly visible to the naked eye. With an annual parallax shift of 12.33 mas, it is located around 260 light years from the Sun. It is member of the nearby Coma Star Cluster (Melotte 111).

The comet became visible to the naked eye from dark-sky sites around February 7. It figured near the double star Zubenelgenubi on February 6, near Spica on February 15 and 16, near Gamma Virginis on February 19 and near the star cluster M44 on March 5 and 6. It also figured near the planetary nebula NGC 2392 on March 14, and near the double star Wasat around March 17.

BO Carinae, also known as HD 93420, is an irregular variable star in the constellation Carina. BO Car has a maximum apparent magnitude of +7.18. Its distance and membership is uncertain, but its possible membership to the star cluster Trumpler 15 allows a distance estimate of approximately (). The Gaia Data Release 2 parallax of suggests a closer distance, but the value is considered unreliable due to excess astrometric noise.

Rangiroa (Tuamotuan for 'vast sky') or Te Kokōta (Cook Islands Māori for 'the Hyades star cluster') is the largest atoll in the Tuamotus and one of the largest in the world (smaller than Kwajalein in the Marshall Islands and Huvadhu in the Maldives). It is part of the Palliser group. The nearest atoll is Tikehau, 12 km to the west. It is about 355 km northeast of Tahiti.

Messier 77 or M77, also known as NGC 1068, is a barred spiral galaxy about 47 million light-years away in the constellation Cetus. Messier 77 was discovered by Pierre Méchain in 1780, who originally described it as a nebula. Méchain then communicated his discovery to Charles Messier, who subsequently listed the object in his catalog. Both Messier and William Herschel described this galaxy as a star cluster.

He developed a numerical technique using Monte Carlo methods to follow the dynamical evolution of a spherical star cluster much faster than the so-called n-body methods. In mathematics, he is well known for the Hénon map, a simple discrete dynamical system that exhibits chaotic behavior. He published a two-volume work on the restricted three-body problem. In 1978 he was awarded the Prix Jean Ricard.

In 1974 the Arecibo message was sent with a radio signal aimed at a star cluster. It consisted of 1679 binary digits intended to be interpreted as a 23 \times 73 bitmap image. The number 1679=23\cdot 73 was chosen because it is a semiprime and therefore can be arranged into a rectangular image in only two distinct ways (23 rows and 73 columns, or 73 rows and 23 columns).

Westerlund 1-237 or Wd 1-237 is a possible red supergiant (RSG) in the constellation of Ara. It is one out of 4 known red supergiants in the Westerlund 1 super star cluster, although its outlying position, spectrum, and parallax, suggest it could be a foreground giant. As a red supergiant, it would be one of the largest known stars and one of most luminous of its type.

However, its neutral hydrogen disk shows a significant amount of warp, suggesting that the outer gas is still settling into place. The mass models of the galaxy suggest the dominant source of mass is a dark matter halo. It has a super star cluster located near the galactic center, and shows strong galactic winds. Designated NGC1750–1, this cluster has a maximum radius of and is Myr old.

Westerlund 1-75 or Wd 1-75 is a red supergiant (RSG) located in the Westerlund 1 super star cluster. Its radius was calculated to be around 668 solar radii (4.65 × 108 km, 3.10 au). This corresponds to a volume 298 million times bigger than the Sun. If placed at the center of the Solar System, Westerlund 1-75 would engulf the inner limits of the asteroid belt.

R136a3 is a Wolf–Rayet star in R136, a massive star cluster located in Dorado. It is located near R136a1, the most massive and luminous star known. R136a3 is itself one of the most massive and most luminous stars known at 180 times more massive and 3.8 million times more luminous than the Sun. The formal name of the star is RMC 136a3, standing for Radcliffe observatory, Magellanic Clouds, 136a3.

The Doron Empire, hailing from the Ganymede system came to Earth in order to conquer it. General Doron already overthrew the queen Medusa of Ganymede in the Magellan star cluster. Earth's defenses were no match; in a matter of days, 95% of the Earth fell under Doron's occupation. Doctor Shikishima, a brilliant scientist, places his last hopes for Earth in a robot (Mechander Robo) that he has created.

NGC 6819 is an open cluster (commonly known as an "open star cluster") located 7,200 light years away in the Cygnus constellation. It was discovered by Caroline Herschel on 12 May 1784. Situated on the boundary of Cygnus and Lyra, NGC 6819 contains roughly two dozen stars of magnitude 10 to 12, with many more lower magnitude members. The age of NGC 6819 is estimated here to be ~ 2.5 ± 0.5 Gyr.

Photometric parallax is a means to infer the distances of stars using their colours and apparent brightnesses. It was used by the Sloan Digital Sky Survey to discover the Virgo super star cluster. Assuming that a star is on the main sequence, the star's absolute magnitude can be determined based on its color. Once the absolute and apparent magnitudes are known, the distance to the star can be determined by using the distance modulus.

Willman 1 is an ultra low-luminosity dwarf galaxy or a star cluster. Willman 1 was discovered in 2004.Space.com, "Puzzling Milky Way Companion Found", Robert Roy Britt, 25 October 2004 (accessed 12 June 2013) It is named after Beth Willman of Haverford College, the lead author of a study based on the Sloan Digital Sky Survey data. The object is a satellite of the Milky Way, at ~120,000 light-years away.

The fleet's food supply has been contaminated, forcing everyone to subsist on rapidly dwindling food rations. Athena, who has been doing reconnaissance, discovers a planet where abundant algae is found that can be used as a nutritious, if unappetizing, food source. Unfortunately, the planet is located on the other side of a vast, highly radioactive star cluster that is too big to go around. The fleet must cross the cluster or risk starvation.

SN 2004dj was the brightest supernova since SN 1987A at the time of its discovery. This Type II-P supernova was discovered by Koichi Itagaki, a Japanese astronomer on July 31, 2004. At the time of its discovery, its apparent brightness was 11.2 visual magnitude; the discovery occurred after the supernova had reached its peak magnitude. The supernova's progenitor is a star in a young, compact star cluster in the galaxy NGC 2403, in Camelopardalis.

NGC 6791 is an open star cluster in the Lyra constellation. It was discovered by Friedrich August Theodor Winnecke in 1853. At roughly 8 billion years old, and with an Iron to Hydrogen abundance ratio that is more than twice that of the Sun, it is one of the oldest and most metal-rich clusters in the Milky Way. This is contrary to the typical rule-of-thumb where older means more metal-poor.

NGC 1854 (also known as NGC 1855) is a young globular cluster in the northern part of the central bar structure of the Large Magellanic Cloud in the Dorado constellation. At 200x magnification the cluster appears very bright, large and round, with dozens of very faint stars visible. NGC 1858, a nebula/star cluster object, lies to the South-East. The cluster was first discovered by Scottish astronomer James Dunlop who observed it in 1826.

Map showing the location of NGC 3766. NGC 3766 (also known as Caldwell 97) is an open star cluster in the southern constellation Centaurus. It is located in the vast star-forming region known as the Carina molecular cloud, and was discovered by Nicolas Louis de Lacaille during his astrometric survey in 1751–1752. At a distance of about 1745 pc, the cluster subtends a diameter of about 12 minutes of arc.

It was with this telescope that he discovered Phobos and Deimos in August 1877. Hall also noticed a white spot on Saturn which he used as a marker to ascertain the planet's rotational period. In 1884, Hall showed that the position of the elliptical orbit of Saturn's moon, Hyperion, was retrograding by about 20° per year. Hall also investigated stellar parallaxes and the positions of the stars in the Pleiades star cluster.

The Serpens South star cluster is embedded in a filamentary molecular cloud, seen as a dark ribbon passing vertically through the cluster. This cloud has served as a testbed for studies of molecular cloud stability. The physics of molecular clouds is poorly understood and much debated. Their internal motions are governed by turbulence in a cold, magnetized gas, for which the turbulent motions are highly supersonic but comparable to the speeds of magnetic disturbances.

Images can be brightened and manipulated in a computer to adjust color and increase the contrast.

The Messier 80 globular cluster in the constellation Scorpius is located about 30,000 light-years from the Sun and contains hundreds of thousands of stars. A globular cluster is a spherical collection of stars that orbits a galactic core. Globular clusters are very tightly bound by gravity, which gives them their spherical shapes, and relatively high stellar densities toward their centers. The name of this category of star cluster is derived from the Latin, globulus—a small sphere.

A quick and daring attack forces the Masters to flee and the human fleet scatters its attackers. In the wreckage of an enemy ship the humans find an intact set of star charts and use them to locate the Masters’ home worlds. Using a new astrogation system, the fleet proceeds directly to the Masters’ star cluster. The Saurians there are completely unprepared and are easily defeated. Jeff then confronts one of the Masters on the Masters’ ancient home world.

The spin axes of the black holes were likely misaligned with the axis of the binary orbit. The probability that both spin axes were positively aligned with the orbit is less than 5%. This configuration suggests that the binary black hole system was formed dynamically in a dense star cluster such as a globular cluster, i.e., as a result of gravitational interaction between stars and binary stars, in which case randomly aligned spin axes are expected.

NGC 1579 (also known as the Northern Trifid) is a diffuse nebula located in the constellation of Perseus. It is referred to as the Northern Trifid because of its similar appearance to the Trifid Nebula, which is located in the southern celestial hemisphere of the sky. It is a H II region, a region of star formation. The star cluster contains the emission-line star LkHα 101, which provides much of the ionizing radiation in the nebula.

Intense study of large numbers of stars suggest that 6.7% of stars with temperatures between and show rapid small-amplitude pulsations but are not members of other variable star classes. These are potentially Maia variables. Maia is surrounded by the Maia Nebula (also known as NGC 1432), a reflection nebula that is one of the brightest patches of nebulosity within the Pleiades star cluster. It is the only member of the New General Catalogue discovered photographically.

47 Tucanae, a globular cluster.Membership in a star cluster or star system permits an assignment of rough ages to a large number of stars present within. When one can determine the age of stars through other methods, such as the ones listed above, one can identify the age of all of the bodies in a system. This is especially useful in clusters of stars which exhibit a large amount of variety in their stellar masses, evolutionary stages, and classifications.

NGC 1931, is an emission and reflection nebula in the constellation Auriga. The nebula has been referred to as a "miniature version of the Orion Nebula", as it shares some of the same characteristics. It is a mixed emission- reflection nebula, and contains a smaller version of the Trapezium in its hot young star cluster centered in the emission nebula. The entire cluster/nebula complex is only about 3 arcminNGC 1931 @ SEDS NGC objects pages in size.

Spaceships can peacefully colonize unoccupied planets or invade inhabited planets and usurp structures. They can also do battle with enemy planets or other ships. Ascendancy's primary display is a three-dimensional rotatable model of the star cluster, which details the star cluster's solar systems, starlanes, and civilizations. The player can "zoom in" to view rotatable models of solar systems (including planets and ships); view a planet's surface and use various screens to manage their fleet, planets and research.

Pleiades seen with the naked-eye (upper-left corner). High visibility of the star cluster Pleiades in the night sky and its position along the ecliptic (which approximates to the solar system's common planetary plane) has given it importance in many cultures, ancient and modern. Its heliacal rising, which moves through the seasons over millennia (see precession) was nonetheless a date of folklore or ritual for various ancestral groups, so too its yearly heliacal setting.Brad Schaefer (Yale University).

The status of this group as a star cluster has changed in recent years. The group was considered to be a cluster for most of the 20th century. Looking at a variety of criteria, however, a study in 1970 concluded that only 6 of the brightest stars formed an actual cluster. Several independent studies since 1998 have now determined that this object is not a true cluster at all, but rather just a chance alignment of stars.

Westerlund 1-20 or Wd 1-20 is a red supergiant (RSG) located in the Westerlund 1 super star cluster. Its radius was calculated to be around 965 solar radii (6.72 × 108 km, 4.48 au), making it one of the largest stars discovered so far. This corresponds to a volume 899 million times bigger than the Sun. If placed at the center of the Solar System, the photosphere of Westerlund 1-20 would almost reach the orbit of Jupiter.

Westerlund 1-20 compared to the other 3 RSGs in the Westerlund 1 star cluster. The star is classified as a luminous cool supergiant emitting most of its energy in the infrared spectrum. W20 occupies the upper right corner of the Hertzsprung-Russell diagram. Using the effective temperature of 3,500 K, the bolometric luminosity of 126,000 L☉ and the solar effective temperature of 5,772 K, its 1-20 can be calculated using the Stefan-Boltzmann law.

According to some versions of the tale, all seven sisters committed suicide because they were so saddened by either the fate of their father, Atlas, or the loss of their siblings, the Hyades. In turn Zeus, the ruler of the Greek gods, immortalized the sisters by placing them in the sky. There these seven stars formed the star cluster known thereafter as the Pleiades. The Greek poet Hesiod mentions the Pleiades several times in his Works and Days.

In March1910 she became their legal guardian. Following the "discovery", Leadbeater began occult examinations of Krishnamurti, to whom he had assigned the pseudonym the name of a star in the Pleiades star cluster, and of characters from Greek mythology. Leadbeater's belief regarding the boy's suitability was strengthened by his clairvoyance-aided investigations of Krishnamurti's reputed past and future lives. Results of these investigations were recorded, and eventually published in Theosophical magazines starting April1910, and in a book in 1913.

The young star cluster NGC 2264, with a large number of T Tauri stars contracting towards the main sequence. The solid line represents the main sequence, while the two lines above that are the 10^{6.5} yr (upper) and 10^{6.7} yr (lower) isochrones. Observational evidence of the Hayashi track comes from color-magnitude plots—the observational equivalent of HR diagrams—of young star clusters. For Hayashi, NGC 2264 provided the first evidence of a population of contracting stars.

Mirsky dies an old woman in space in 3354. In their last conversation, they discuss the Greenfly, which they observe by now has begun spreading to other systems, destroying the intelligent societies it was designed to provide for. All attempts at containing the swarm have failed. In 4161, Irravel stops at the Pleiades cluster and meets distant descendants of the Conjoiners living amongst a race known as the Islanders, who inhabit the planets in the star cluster.

NGC 457 (also known as the Owl Cluster, the E.T. Cluster, or Caldwell 13) is an open star cluster in the constellation Cassiopeia. It was discovered by William Herschel in 1787, and lies over 7,900 light years away from the Sun. It has an estimated age of 21 million years. The cluster is sometimes referred by amateur astronomers as the Owl Cluster, the E.T. Cluster (due to its resemblance to the movie character) or the "Skiing Cluster".

Because of the faintness of the lowest-luminosity dwarf spheroidal galaxies and the nature of the stars contained within them, some astronomers suggest that dwarf spheroidal galaxies and globular clusters may not be clearly separate and distinct types of objects. Other recent studies, however, have found a distinction in that the total amount of mass inferred from the motions of stars in dwarf spheroidals is many times that which can be accounted for by the mass of the stars themselves. Studies reveal that dwarf spheroidal galaxies have a dynamical mass of around 10^7 solar masses, which is very large despite the low luminosity of dSph galaxies. Although at fainter luminosities of dwarf spheroidal galaxies, it is not universally agreed upon how to differentiate between a dwarf spheroidal galaxy and a star cluster; however, many astronomers decide this depending on the object's dynamics: if it seems to have more dark matter, then it is likely that it is a dwarf spheroidal galaxy rather than a faint star cluster.

The Lambda Orionis Cluster (also known as the Collinder 69) is an open star cluster located north-west of the star Betelgeuse in the constellation of Orion. It is about five million years old and roughly away from the Sun. Included within the cluster is a double star named Meissa. With the rest of Orion, it is visible from the middle of August in the morning sky, to late April before Orion becomes too close to the Sun to be seen well.

The cluster is following an orbit through the Milky Way that has a period of 227.4 million years with an ellipticity of 0.06, carrying it as far as from the Galactic Center, and as close as . The inclination of the orbit carries it up to away from the galactic plane. On average it crosses the plane every 33.3 million years. The star cluster is young and contains a large number of low-mass stars, some T Tauri stars and brown dwarfs.

The stars of Com were probably among the first stars to form in the Universe and currently there is no star formation in Com. The measurements have so far failed to detect any neutral hydrogen in it—the upper limit is only 46 solar masses. Coma Dwarf is located near the Sagittarius Stream, which is made of stars stripped from the Sagittarius Dwarf Elliptical Galaxy. This association may indicate that Com is a former satellite of star cluster from that galaxy.

In the end he gave the company a Japanese name that he "had been cherishing in his heart": Subaru, which is the Japanese name for the Pleiades star cluster. The first Subaru car was named the Subaru 1500. Only twenty were manufactured owing to multiple supply issues. Subsequently, the company designed and manufactured dozens of vehicles including the 1500 (1954), the tiny air-cooled 360 (1958), the Sambar (1961), and the 1000 (which saw the introduction of the Subaru boxer engine in 1965).

Heavier stars slow down and crowd at the cluster's core, while lighter stars pick up speed and tend to spend more time at the cluster's periphery. The globular star cluster 47 Tucanae, which is made up of about 1 million stars, is one of the densest globular clusters in the Southern Hemisphere. This cluster was subjected to an intensive photographic survey, which allowed astronomers to track the motion of its stars. Precise velocities were obtained for nearly 15,000 stars in this cluster.

Messier 10 lies about 15,000 light- years from Earth, in the constellation of Ophiuchus. The distinction between cluster types is not always clear-cut, and objects have been found that blur the lines between the categories. For example, BH 176 in the southern part of the Milky Way has properties of both an open and a globular cluster. In 2005, astronomers discovered a completely new type of star cluster in the Andromeda Galaxy, which is, in several ways, very similar to globular clusters.

Rainer Spurzem is a German astronomer at the Astronomisches Rechen-Institut in Heidelberg, Germany. His speciality is the N-body simulation of galaxies and star clusters.Spurzem, R.

Maia , designated 20 Tauri (abbreviated 20 Tau), is a star in the constellation of Taurus. It is a blue giant of spectral type B8 III, a chemically peculiar star, and the prototype of the Maia variable class of variable star. Maia is the fourth-brightest star in the Pleiades open star cluster (Messier 45), after Alcyone, Atlas and Electra. It is surrounded by one of the brighter reflection nebulae within the Pleiades, designated NGC 1432 and sometimes called the Maia Nebula.

The name Maia originates with the and . Maia is one of the seven daughters of Atlas and Pleione in Greek mythology--stars which are also included in the Pleiades star cluster. In 2016, the International Astronomical Union organized a Working Group on Star Names (WGSN) to catalog and standardize proper names for stars. The WGSN's first bulletin of July 2016 included a table of the first two batches of names approved by the WGSN; which included Maia for this star.

The beginning of Makahiki generally is fixed each year by astronomical observations. On the Island of Hawaiʻi, when Makaliʻi (Pleiades) star cluster rises shortly after sunset, usually on November 17, the rising of the following first crescent moon marks the beginning of the season. On Oʻahu, it may begin when Makaliʻi rises above Puʻu o Mahuka Heiau, as seen from Kaena Point, or when the star ʻAʻa (Sirius) appears in conjunction with a particular land form high on a cliff.

La Pléiade () is the name given to a group of 16th-century French Renaissance poets whose principal members were Pierre de Ronsard, Joachim du Bellay and Jean-Antoine de Baïf. The name was a reference to another literary group, the original Alexandrian Pleiad of seven Alexandrian poets and tragedians (3rd century B.C.), corresponding to the seven stars of the Pleiades star cluster. The name "Pléiade" was also adopted in 1323 by a group of fourteen poets (seven men and seven women) in Toulouse.

Chase Kolpath visits Alex at his uncle's house. Before disappearing, Gabriel Benedict had hired Ms. Kolpath to investigate the last flight of the Tenandrome, Hugh Scott's Planetary Survey ship, and then meet Gabe at a world near the Veiled Lady star cluster and pilot them to an unspecified destination. Alex's uncle disappeared before reaching his destination, and owed Ms. Kolpath a considerable sum. Alex agrees to pay what his uncle owed her and asks her to assist him in his investigations.

Infant star CARMA-7 and its jets are located approximately 1400 light-years from Earth within the Serpens South star cluster. Star formation begins in relatively small molecular clouds called dense cores. Each dense core is initially in balance between self-gravity, which tends to compress the object, and both gas pressure and magnetic pressure, which tend to inflate it. As the dense core accrues mass from its larger, surrounding cloud, self-gravity begins to overwhelm pressure, and collapse begins.

Two of the cluster's star systems are likely eclipsing binaries with periods of 0.6 and 1.03 days. NGC 663 also has two red supergiant stars, both located on its periphery The star cluster is assumed to form part of the stellar association Cassiopeia OB8, that is located in the Perseus arm of the Milky Way, along with the open clusters M103, NGC 654, NGC 659, and some supergiant stars scattered between them, all of them having similar ages and distances.

Portion of the Carina Nebula Around 150 AD, Ptolemy recorded, in books VII–VIII of his Almagest, five stars that appeared nebulous. He also noted a region of nebulosity between the constellations Ursa Major and Leo that was not associated with any star. The first true nebula, as distinct from a star cluster, was mentioned by the Persian astronomer Abd al-Rahman al-Sufi, in his Book of Fixed Stars (964). He noted "a little cloud" where the Andromeda Galaxy is located.

He discovered that many of these features could be resolved into groupings of individual stars. Herschel conceived the idea that stars were initially scattered across space, but later became clustered together as star systems because of gravitational attraction. He divided the nebulae into eight classes, with classes VI through VIII being used to classify clusters of stars. NGC 265, an open star cluster in the Small Magellanic Cloud The number of clusters known continued to increase under the efforts of astronomers.

Westerlund 1-75 compared to the other 3 RSGs in the Westerlund 1 star cluster. The star is classified as a luminous cool supergiant emitting most of its energy in the infrared spectrum. It occupies the upper right corner of the Hertzsprung- Russell diagram. Using the effective temperature of 3,600 K, the bolometric luminosity of 68,000 L☉ and the solar effective temperature of 5,772 K, the radius of Westerlund 1-75 can be calculated using the Stefan-Boltzmann law.

Elnath's absolute magnitude is -1.34, similar to another star in Taurus, Maia in the Pleiades star cluster. Like Maia, β Tauri is a B-class giant with a luminosity 700 times solar. It has evolved away from the main sequence to become a giant star, larger and cooler than when it was on the main sequence. However, being approximately 130 light-years distant compared to Maia's estimated 360 light-years, β Tauri ranks as the second-brightest star in the constellation.

As Altares leaves the Solar System, Jane and David observe how Pluto turns blue then red due to the shortening and subsequent lengthening of light waves caused by the Doppler effect. Arriving at Alpha Centauri, the crew launch a series of satellites that will transmit data back to Earth. Having completed their primary objective, they agree to push deeper into space. When Altares encounters a star cluster, Anna tells Jane of Einstein's discoveries in the fields of special relativity and unified field theory.

14 Comae Berenices is a single star in the northern constellation of Coma Berenices, and is the second brightest member of the Coma Star Cluster. It is a faint star but visible to the naked eye with an apparent visual magnitude of 4.95. Parallax measurements place the star at a distance of about 266 light years. The spectrum of this star is peculiar and it has been assigned a number of different stellar classifications: A5, F0p, , F0 vp, , , F1 IV, and .

19 Tauri is a double star in the constellation of Taurus and a member of the Pleiades open star cluster (M45). It consists of a binary pair designated 19 Tauri A together with a single star visual companion, 19 Tauri B. 'A's' two components are themselves designated 19 Tauri Aa (officially named Taygeta , the traditional name for the entire system) and Ab. Based on parallax measurements obtained during the Hipparcos mission, 19 Tauri A is approximately 440 light-years from the Sun.

Pleione (pronounced or ) is a binary star and the seventh-brightest star in the Pleiades star cluster (Messier 45). It has the variable star designation BU Tauri (BU Tau) and the Flamsteed designation 28 Tauri (28 Tau). The star is located approximately from the Sun, appearing in the constellation of Taurus. Pleione is located close on the sky to the brighter star Atlas, so is difficult for stargazers to distinguish with the naked eye despite being a fifth magnitude star.

He then computed the evolutionary tracks and isochrones (luminosity- temperature distributions of stars at a given age) for a variety of stellar masses and noted that NGC2264, a very young star cluster, fits the isochrones well. In particular, he calculated much lower ages for solar-type stars in NGC2264 and predicted that these stars were rapidly contracting T Tauri stars. In 1962, Hayashi published a 183-page review of stellar evolution. Here, he discussed the evolution of stars born in the forbidden region.

It is also associated with a nearby star cluster that contains several massive stars. Sharpless 2-88B2 is a HII region ionized by a star that is dimmer than B0.5 V, and is ultracompact. HD 338916 is an emission line star that ionizes a close nebula in the Vulpecula OB1 association. It has an apparent magnitude (V) of 10.17 and a spectral type of O8 D. HD 338926 is another emission line star that ionizes a close nebula in the Vulpecula OB1 association.

In some cases, the formation of a large star cluster within an H II region results in the region being hollowed out from within. This is the case for NGC 604, a giant H II region in the Triangulum Galaxy. For a H II region which cannot be resolved, some information on the spatial structure (the electron density as a function of the distance from the center, and an estimate of the clumpiness) can be inferred by performing an inverse Laplace transform on the frequency spectrum.

Map showing the location of NGC 2232 NGC 2232 is a bright open star cluster in the equatorial constellation of Monoceros, centered on the star 10 Monocerotis. It is located in the Gould Belt close to the Orion Nebula cluster, at a mean distance of from the Sun. The average radial velocity of the cluster members is . This is one of the nearest open clusters to the Sun, which makes it a potentially useful target for studying young stars and their transition to the main sequence.

The Orion Nebula consists of one of the nearest (thus in the Milky Way Galaxy), massive molecular clouds (30 - 40 light years in diameter) about 1,300 light years from the solar system. This makes the nebula potentially the closest HII region to Earth, a mass of hydrogen that has been ionized by nearby, hot, young stars. Regions like this are called stellar nurseries, nurturing the birth of multiple young stars such as the Orion Nebula Star Cluster. These are a hallmark of the asterism.

Such a scenario may mean that Proxima's planetary companions have had a much lower chance for orbital disruption by Alpha Centauri. Six single stars, two binary star systems, and a triple star share a common motion through space with Proxima Centauri and the Alpha Centauri system. The space velocities of these stars are all within 10 km/s of Alpha Centauri's peculiar motion. Thus, they may form a moving group of stars, which would indicate a common point of origin, such as in a star cluster.

The piano that Kara Thrace plays in the episode "Someone to Watch Over Me" is located in Joe's Bar. In the episode "The Passage" Galactica was used to house fleet passengers during the trip through a star cluster, leaving the fleet vessels to be flown by skeleton crews with radiation medication. Galactica was seen taking multiple hits from Cylon nuclear weapons and though the ship suffered damage, she was still operational. It is unclear exactly how well rated the Cylon nuclear weapons were versus Galacticas armor.

M 71 from Calar Alto Observatory 1995, T. Credner and S. Kohle Messier 71 (also known as M71 or NGC 6838) is a globular cluster in the constellation Sagitta. It was discovered by Philippe Loys de Chéseaux in 1745 and included by Charles Messier in his catalog of non-comet-like objects in 1780. It was also noted by Koehler at Dresden around 1775. The star cluster is at a distance of about 12,000 light years away from Earth and spans some 27 light years across.

Mons Pico, one of the Montes Teneriffe range of lunar mountains in the inner ring of the Mare Imbrium, was named by Johann Hieronymus Schröter after the Pico von Teneriffe, an 18th-century name for Teide.Sheehan, William & Baum, Richard, Observation and inference: Johann Hieronymous Schroeter, 1745–1816, JBAA 105 (1995), 171Schroeter, Johann Hieronymous, Selenotopographische Fragmente sur genauern Kenntniss der Mondfläche [vol. 1]. – Lilienthal: auf Kosten des Verfassers, 1791 There is also a brown dwarf star located in the open star cluster of the Pleiades called Teide 1.

However, secular parallax introduces a higher level of uncertainty because the relative velocity of observed stars is an additional unknown. When applied to samples of multiple stars, the uncertainty can be reduced; the uncertainty is inversely proportional to the square root of the sample size. Moving cluster parallax is a technique where the motions of individual stars in a nearby star cluster can be used to find the distance to the cluster. Only open clusters are near enough for this technique to be useful.

The Kappa Cygnids take place in August, with the dates varying each year. The Alpha Capricornids meteor shower takes place as early as July 10 and ends at around August 10, and the Southern Delta Aquariids take place from mid-July to mid-August, with the peak usually around July 28–29. The Perseids, a major meteor shower, typically takes place between July 17 and August 24, with the days of the peak varying yearly. The star cluster of Messier 30 is best observed around August.

Other open clusters were noted by early astronomers as unresolved fuzzy patches of light. In his Almagest, the Roman astronomer Ptolemy mentions the Praesepe cluster, the Double Cluster in Perseus, the Coma Star Cluster, and the Ptolemy Cluster, while the Persian astronomer Al-Sufi wrote of the Omicron Velorum cluster. However, it would require the invention of the telescope to resolve these "nebulae" into their constituent stars. Indeed, in 1603 Johann Bayer gave three of these clusters designations as if they were single stars.

Merope is a cluster composed of repurposed Intel Xeon X5670 (Westmere) processors that were once part of the Pleiades supercomputer. The system is used both for running real-world computational jobs for NASA scientists and engineers and for testing purposes. Housed in an auxiliary processing center located about 1 kilometer from the NAS facility at NASA Ames Research Center. Merope (pronounced MEH-reh-pee) is named after one of the seven stars that make up the Pleiades open star cluster in the constellation Taurus.

7 Comae Berenices is a single star located 249 light years away in the northern constellation of Coma Berenices. It is a dim star but visible to the naked eye near the Coma Star Cluster with an apparent visual magnitude of 4.93. The star is moving closer to the Earth with a heliocentric radial velocity of −28 km/s, and is predicted to come as close as in 2.4 million years. This is an evolved giant star with a stellar classification of G8 III–IIIb.

During a brief speech he gave to the troops, he called out "OORAH!" His call was answered by enthusiastic Marines, who showed even greater energy and motivation moments later as the General's speech was interrupted by the call of, "White Star Cluster!" by a Marine at an observation post. The Marines quickly grabbed their gear and weapons and ran to their fighting positions where they waited for either combat or the sounding of 'all clear'. The Marines returned to their duties when an "all clear" was given.

Dark star- forming regions within the Eagle Nebula commonly referred to as the Pillars of Creation A few of the brightest H II regions are visible to the naked eye. However, none seem to have been noticed before the advent of the telescope in the early 17th century. Even Galileo did not notice the Orion Nebula when he first observed the star cluster within it (previously cataloged as a single star, θ Orionis, by Johann Bayer). The French observer Nicolas-Claude Fabri de Peiresc is credited with the discovery of the Orion Nebula in 1610.

The data were processed using the Astro-WISE software system developed by E.A. Valentijn and collaborators at Groningen and elsewhere. The second released VST image (top on the right) may be the best portrait of the globular star cluster Omega Centauri ever made. Omega Centauri, in the constellation of Centaurus (The Centaur), is the largest globular cluster in the sky, but the very wide field of view of VST and its powerful camera OmegaCAM can encompass even the faint outer regions of this object. The view seen on the left includes about 300 000 stars.

The SMBH itself is dark and undetectable, but its gravity causes the stars to move at much higher velocities than in an ordinary star cluster. Normal star clusters have internal velocities of a few kilometers per second, while in an HCSS, essentially all the stars are moving faster than , i.e. hundreds or thousands of kilometers per second. If the kick velocity is less than the escape velocity from the galaxy, the SMBH will fall back toward the galaxy nucleus, oscillating many times through the galaxy before finally coming to rest.

In Saga of a Star World, he was one of the three recipients (Apollo and Starbuck being the other two) of the Golden Star Cluster, the highest military honor that could be awarded to Colonial Service warriors (similar to the Medal of Honor for the real-world United States armed forces). During the events of Galactica 1980, Boomer had reached the rank of colonel and was the executive officer of the Battlestar Galactica. Richard Hatch's re-launch novel series sees him promoted to major and still serving as a Viper pilot.

Scientists that have conducted research at Oxford have made contributions to science including developments in technology and applications in the medical fields. An astronomer named Edmund Halley was a young astronomer who made discoveries in relation to the stars. The young astronomer sailed to an island named St. Helena to make observations of stars and broaden his star catalogue. Edmund became the first person to make telescopic observations of the stars in the southern hemisphere and had discovered a star cluster in the constellation of Centaurus during the 1690s.

Proxima's orbital period around the Alpha Centauri AB barycenter is years with an eccentricity of ; it approaches Alpha Centauri to at periastron and retreats to at apastron. At present, Proxima is from the Alpha Centauri AB barycenter, nearly to the farthest point in its orbit. Such a triple system can form naturally through a low-mass star being dynamically captured by a more massive binary of within their embedded star cluster before the cluster disperses. However, more accurate measurements of the radial velocity are needed to confirm this hypothesis.

In the mythology of the Aboriginal people of south-eastern Australia, the Karatgurk were seven sisters who represented the Pleiades star cluster. According to a legend told by the Wurundjeri people of the Kulin nation, in the Dreamtime the Karatgurk alone possessed the secret of fire. Each one carried a live coal on the end of her digging stick, allowing them to cook the yams which they dug out of the ground. The sisters refused to share their coals with anybody, however they were ultimately tricked into giving up their secret by Crow.

The Quyllurit'i festival takes place at the end of a period of a few months when the Pleiades constellation, or Seven Sisters, a 7-star cluster in the Taurus constellation, disappears and reappears in the skies of the Southern Hemisphere. Its time of disappearance was marked in Inca culture by a festival for Pariacaca, the god of water and torrential rains. It occurs near the date of qarwa mita (qarwa meaning when the corn leaves are yellow).Antoinette Molinié Fioravanti, Celebrando el Cuerpo de Dios (Corpus Christi Festival), Fondo Editorial PUCP, 1999, pp.

They have similar distribution to the stellar disk of NGC 1380 and have slightly higher metallicity than the globular clusters in the Milky Way, and are associated with the bulge of the galaxy. Based on their size, there are three star cluster populations, the typical globular clusters, with effective radius under 3 kpc, the diffuse star clusters, with effective radius circa 5 kpc, and the faint fuzzy clusters, with effective radius over 8 kpc. The typical globular clusters are closer to the nucleus than the diffuse star clusters.

The Terrans are depicted as diversified, individualistic and fragmented, with multiple factions vying for dominance over each other. Numerous factions are used throughout the series, ranging from national governments and corporations to rebels and criminals, although only four "Government" factions exhibit any major influence on the overall story arc. The Koprulu sector—nicknamed the "Terran Sector"— is a fictional star cluster in space colonized by terrans that infringes upon Protoss imperial territory, with frequent incursions from the Zerg. It is situated on the galactic fringe of the Milky Way, 60,000 light years from Earth.

The narrator of the story implies that the person named Hali is now dead (at least in the timeline of the story). Several other nearly undescribed places are alluded to in Chambers' writing, among them Hastur, Yhtill, and Aldebaran. "Aldebaran" may refer to the star Aldebaran, likely as it is also associated with the mention of the Hyades star cluster, with which it shares space in the night sky. The Yellow Sign, described as a symbol, not of any human script, is supposed to originate from the same place as Carcosa.

After two supermassive black holes coalesce, emission of linear momentum can produce a "kick" with amplitude as large as 4000 km/s. This is fast enough to eject the coalesced black hole completely from its host galaxy. Even if the kick is too small to eject the black hole completely, it can remove it temporarily from the nucleus of the galaxy, after which it will oscillate about the center, eventually coming to rest. A kicked black hole can also carry a star cluster with it, forming a hyper-compact stellar system.

Earth's own Sun is considered to have descended from multiple generations of stars, as evidenced by heavy elements found, in the Solar System, in concentrations too large for a first-time star. Detailed observations of a star cluster nebula provide astronomers with a laboratory for understanding the early universe, and stellar birth and death cycles. Henize 206 was first catalogued in the early 1950s by Dr. Karl Henize, an astronomer who became a NASA astronaut. He flew during the Spacelab-2 mission, aboard the Space Shuttle Challenger in July/August 1985.

This is an aging giant star with a stellar classification of K0III, having evolving off the main sequence after the supply of hydrogen at its core was exhausted. It is an estimated 4.78 billion years old with 1.39 times the mass of the Sun, although Bailer-Jones et al. (2018) give a higher estimate of 2.8 times the Sun's mass. The elemental composition of this star has made it the first giant to be a candidate solar sibling, suggesting it may have been born in the same star cluster as the Sun.

The existence of this nuclear star cluster doesn't rule out the existence of a supermassive black hole. Galaxies like the Milky Way and the Andromeda Galaxy have been found to host both. The stellar population at the nucleus of NGC 7418 has been found to be quite young, with mean age less than 100 million years, indicating recent star forming activity. One supernova has been observed in NGC 7418, SN 1983 Z. It was discovered by L. E. Gonzalez at Cerro El Roble 11" west and 52" south of the nucleus.

NGC 2060 is a star cluster within the Tarantula Nebula in the Large Magellanic Cloud, very close to the larger NGC 2070 cluster containing R136. It was discovered by John Herschel in 1836. It is a loose cluster approximately 10 million years old, within one of the Tarantula Nebula's superbubbles formed by the combined stellar winds of the cluster or by old supernovae. NGC 2060 is often used synonymously for the supernova remnant N157B (30 Doradus B) which is a larger area of faint nebulosity and strong radio emission.

NGC 1850 is a double cluster and a super star cluster in the Dorado constellation, located in the northwest part of the bar of the Large Magellanic Cloud, at a distance of from the Sun. It was discovered by Scottish astronomer James Dunlop in 1826. This is an unusual cluster system because the main distribution of stars is like a globular cluster, but unlike the globular clusters of the Milky Way it is composed of young stars. The only similar object in the Milky Way is Westerlund 1.

Young star ejecting two jets of energised gas. Various methods and tools are involved in stellar age estimation, an attempt to identify within reasonable degrees of confidence what the age of a star is. These methods include stellar evolutionary models, membership in a given star cluster or system, fitting the star with the standard spectral and luminosity classification system, and the presence of a protoplanetary disk, among others. Nearly all of the methods of determining age require knowledge of the mass of the star, which can be known through various methods.

NGC 1763 (also known as ESO 85-EN20) is an emission nebula with an embedded star cluster in the Dorado constellation in the Large Magellanic Cloud, It is very bright, very large and very irregular. Its apparent size is about 3.0-5.0 arcmin. It is part of a large region of stars called LMC-N11 (N11) which was discovered with a 23-cm telescope by the astronomer James Dunlop in 1826 and was also observed by John Herschel in 1834. The nebula itself is catalogued under LHA 120-N 11B or ESO 85-EN20.

IC 4653 galaxy taken by Hubble. The northwest corner of Ara is crossed by the galactic plane of the Milky Way and contains several open clusters (notably NGC 6200) and diffuse nebulae (including the bright cluster/nebula pair NGC 6188 and NGC 6193). The brightest of the globular clusters, sixth magnitude NGC 6397, lies at a distance of just , making it one of the closest globular clusters to the Solar System. Ara also contains Westerlund 1, a super star cluster containing itself the red supergiant Westerlund 1-237 and the red hypergiant Westerlund 1-26.

He also cataloged the Omicron Velorum star cluster as a "nebulous star" and other nebulous objects, such as Brocchi's Cluster. The supernova that created the Crab Nebula, the SN 1054, was observed by Arabic and Chinese astronomers in 1054. In 1610, Nicolas-Claude Fabri de Peiresc discovered the Orion Nebula using a telescope. This nebula was also observed by Johann Baptist Cysat in 1618. However, the first detailed study of the Orion Nebula was not performed until 1659, by Christiaan Huygens, who also believed he was the first person to discover this nebulosity.

Depending on the observer's latitude many stars are subject to annual heliacal risings and settings. Rising means the local latitude of the earth has moved along its orbit such that the star, star cluster or galaxy emerges for part of the year to within months be visible for the whole night and then for the early portion of the night. Thus the star's first emergence, an annual rise, is immediately before dawn. The risen status of each star is easiest considered day-on-day in the tropics where the time of dawn varies less.

Price-Whelan 1 is about ten degrees offset from the leading arm II. This difference is explained with the gas experiencing ram pressure as it passes through the hot gas of the Milky Way halo. The stars will not feel this force. Over time the gas and the stars will decouple, resulting in a different position and velocity for both components. Another possible origin of the star cluster could be the high- velocity cloud HVC 287.5+22.5+240, which has a similar metallicity compared with Price-Whelan 1.

Serpens South is a star cluster embedded in a dense molecular filament containing numerous protostars. Due to the large number of protostars and pre-stellar cores in the region, it is likely that Serpens South has the most star- formation activity in the Serpens-Aquila Rift. A large scale magnetic field was discovered in the region which is perpendicular to the main cloud filament, but sub-filaments tend to run parallel to the filament. This magnetic field may be responsible for slowing the gravitational collapse of molecular clumps in the complex.

Forming the profile of a Bull's face is a V or K-shaped asterism of stars. This outline is created by prominent members of the Hyades, the nearest distinct open star cluster after the Ursa Major Moving Group. In this profile, Aldebaran forms the bull's bloodshot eye, which has been described as "glaring menacingly at the hunter Orion", a constellation that lies just to the southwest. The Hyades span about 5° of the sky, so that they can only be viewed in their entirety with binoculars or the unaided eye.

There has been significant debate as to the star's actual distance from Earth. The debate revolves around the different methodologies to measure distance—parallax being the most central, but photometric and spectroscopic observations yielding valuable insights as well. Before the Hipparcos mission, the estimated distance for the Pleiades star cluster was around 135 parsecs or 440 light years. However, when the Hipparcos Catalogue was published in 1997, the new parallax measurement indicated a much closer distance of about 119 ± 1.0 pc (388 ± 3.2 ly), triggering substantial controversy among astronomers.

Between the two bright stars is a binary star made up of two 9th magnitude stars, Kappa Tauri C and Kappa Tauri D, which are 5.5 arcseconds from each other (as of 2013) and 175.1 arcseconds from κ1 Tau. Two more 12th magnitude companions fill out the visual group: Kappa Tauri E, which is 145 arcseconds from κ1 Tau, and Kappa Tauri F, 108.5 arcseconds away from κ2 Tau. The bright pair are both members of the Hyades star cluster, while the fainter stars are all much more distant background stars.

Westerlund 1-26 or Wd 1-26 is a red supergiant within the outskirts of the Westerlund 1 super star cluster. It is one of the largest known stars discovered so far although its radius is uncertain but is calculated to be either , with a possible but very unlikely upper estimate of , corresponding to a volume between 3.58 or 16.58 billion times bigger than the Sun. Assuming the upper estimate is correct, if placed at the center of the Solar System, its photosphere would engulf the orbit of Saturn.

After Starbuck and Apollo are transferred to the battlestar Pegasus, Kat seems to act as the Galactica 's de facto CAG, and in the months after their return, the rivalry between Kat and Starbuck intensifies. After settlement of New Caprica, Kat is promoted to Captain and becomes the Galactica's CAG; she and Racetrack leads the decoy operation that allow the rescue of the civilian population. After the escape, Apollo is reinstated as CAG; Kat and Starbuck become squadron leaders. When the fleet attempts passage through a highly-radioactive star cluster, Starbuck discovers Kat's past and threatens to reveal it.

These companies were: Fuji Kogyo, a scooter manufacturer; coachbuilder Fuji Jidosha; engine manufacturer Omiya Fuji Kogyo; chassis builder Utsunomiya Sharyo and the Tokyo Fuji Sangyo trading company. Former logo on a Subaru 360 showing six stars in an arrangement similar to the Pleiades open star cluster alt= Kenji Kita, CEO of Fuji Heavy Industries at the time, wanted the new company to be involved in car manufacturing and soon began plans for building a car with the development code-name P-1. Kita canvassed the company for suggestions about naming the P1, but none of the proposals were appealing enough.

Globular star cluster Omega Centauri as seen by the VST. In planetary science, the survey telescope aims to discover and study remote Solar System bodies such as trans-Neptunian objects, as well as search for extrasolar planet transits. The Galactic plane will also be extensively studied with VST, which will look for signatures of tidal interactions in the Milky Way, and will provide astronomers with data crucial to understand the structure and evolution of our Galaxy. Further afield, the VST will explore nearby galaxies, extragalactic and intra-cluster planetary nebulae, and will perform surveys of faint object and micro-lensing events.

In the Antennae galaxy, for example, the Hubble Space Telescope has observed clusters of clusters, regions in the galaxy that span hundreds of parsecs, where many of the clusters will eventually collide and merge. Many of them present a significant range in ages, hence possibly metallicities, and their merger could plausibly lead to clusters with a bimodal or even multiple distribution of populations. Globular star cluster Messier 54. Observations of globular clusters show that these stellar formations arise primarily in regions of efficient star formation, and where the interstellar medium is at a higher density than in normal star-forming regions.

In addition, X-ray observations have revealed the presence of the anomalous X-ray pulsar CXO J164710.20-455217, a slow rotating neutron star that must have formed from a high-mass progenitor star. Westerlund 1 is believed to have formed in a single burst of star formation, implying the constituent stars have similar ages and compositions. Aside from hosting some of the most massive and least-understood stars in our galaxy, Westerlund 1 is useful as a relatively nearby, easy to observe super star cluster that can help astronomers determine what occurs within extragalactic super star clusters.

Estimates of brown dwarf populations in the solar neighbourhood estimated that there may be as many as six stars for every brown dwarf. A more recent estimate from 2017 using the young massive star cluster RCW 38 found that the Milky Way galaxy contains between 25 and 100 billion brown dwarfs. In a study published in Aug 2017 NASA's Spitzer Space Telescope monitored infrared brightness variations in brown dwarfs caused by cloud cover of variable thickness. The observations revealed that large-scale waves propagating in the atmospheres of brown dwarfs (similarly to the atmosphere of Neptune and other Solar System giant planets).

After the first expedition to the Chi Persei cluster a newly formed invasion force of human kind and their allies sets of. Their goals are to find the still missing André, to establish a permanent contact to the Galaxians and to confine the Destroyers. Eli Gamasin, now admiral of the expedition force, is commanding a fleet of powerful ships. First attempts to penetrate the barriers of the star cluster fail but finally the Destroyers are able to trap three ships and to take the crews of these cruisers including Eli Gamasin and his family as prisoners of war.

CXOU J164710.2−455216 is an anomalous X-ray pulsar in the massive galactic open cluster Westerlund 1. It is the brightest X-ray source in the cluster, and was discovered in 2005 in observations made by the Chandra X-ray observatory. Westerlund 1: Neutron Star Discovered Where a Black Hole Was Expected The Westerlund 1 cluster is believed to have formed in a single burst of star formation,On the massive stellar population of the super star cluster Westerlund 1, Clark et al.

Historical light curves of W Sagittarii and Eta AquilaeOn September 10, 1784 Edward Pigott detected the variability of Eta Aquilae, the first known representative of the class of classical Cepheid variables. However, the namesake for classical Cepheids is the star Delta Cephei, discovered to be variable by John Goodricke a month later. Delta Cephei is also of particular importance as a calibrator for the period-luminosity relation since its distance is among the most precisely established for a Cepheid, thanks in part to its membership in a star cluster and the availability of precise Hubble Space Telescope and Hipparcos parallaxes.

The city was later used more extensively in Robert W. Chambers' book of short horror stories published in 1895, titled The King in Yellow. Chambers had read Bierce's work and borrowed a few additional names from his work, including Hali and Hastur. In Chambers' stories, and within the apocryphal play titled The King in Yellow, which is mentioned several times within them, the city of Carcosa is a mysterious, ancient, and possibly cursed place. The most precise description of its location is the shores of Lake Hali, in the star cluster Hyades, either on another planet, or in another universe.

NGC 7822 is a young star forming complex in the constellation of Cepheus. The complex encompasses the emission region designated Sharpless 171, and the young cluster of stars named Berkeley 59. The complex is believed to be some 800–1000 pc distant,Majaess D., Turner D., Lane D., Moncrieff K. (2008). The Exciting Star of the Berkeley 59/Cepheus OB4 Complex and Other Chance Variable Star Discoveries, Journal of the American Association of Variable Star Observers, vol. 36, no. 1, p. 90Pandey et al.(2008).Stellar contents and star formation in the young star cluster Be 59, MNRAS, Volume 383, Issue 3, pp.

Segue 3 is a faint star cluster of the Milky Way galaxy discovered in 2010 in the data obtained by Sloan Digital Sky Survey. It is located in the Pegasus constellation at the distance of about 17 kpc from the Sun and moves away from it with the velocity of . Segue 3 is extremely faint—its visible absolute magnitude is estimated at −1.2 or even at about , which means that the cluster is only 100 to 250 times brighter than the Sun. Its small radius—of about 2.1 pc—is typical for the galactic globular clusters.

NGC 4244, also known as Caldwell 26, is an edge-on loose spiral galaxy in the constellation Canes Venatici, and is part of the M94 Group or Canes Venatici I Group, a galaxy group relatively close to the Local Group containing the Milky Way.. It is located near the yellow naked-eye star, Beta Canum Venaticorum, but also near the barred spiral galaxy NGC 4151 and irregular galaxy NGC 4214. At +10.2v or 10.7B magnitude, NGC 4244 lies approximately 4.1 megaparsecs (14 million light years) away. A nuclear star cluster and halo is located near the centre of this galaxy.

Luminous blue variables have traditionally been considered to be in a short-lived unstable transition state before a massive star becomes a Wolf–Rayet star. This has been challenged by the theory that LBVs are the result of binary mass transfer with the mass gaining star becoming a massive and unstable luminous blue variable. R71 appears to be a very massive star that did not form within a mass star cluster, making it likely that it did not initially form as a very massive star. Instead it may have become massive later by gaining mass from a companion.

Other abilities, such as the Chronomyst traveling quickly through star lanes, are continually active. All opponent species (numbering from two to six) are controlled by a computer AI and are selected randomly. The star density in each game determines how many solar systems exist in the star cluster - the higher the density the more planets that are available to colonize. Star density affects both the length of the game, as large star clusters will take longer to conquer, as well as affecting how quickly species will encounter each other and how much room they have to grow.

HD 97950, is a multiple star system and part of a super star cluster within the NGC 3603 H II region. It was catalogued as a single star although it was always known to be a compact cluster. It is now resolved into a massive multiple star at the centre of one of the densest clusters in the galaxy. Only the six lettered stars A-F at the core of the cluster are typically referred to as components of HD 97950, while the remaining stars of the cluster and surrounding area are usually numbered as members of NGC 3603.

Westerlund 1-237 compared to the other 3 RSGs (Red Supergiants) in the Westerlund 1 star cluster. Westerlund 1-237 is classified as a luminous cool supergiant emitting most of its energy in the infrared spectrum. It is surrounded by a radio nebula which is similar in mass to those of Westerlund 1-20 and Westerlund 1-26, and moreover directly comparable to that of VY Canis Majoris. The elliptical structure of this nebula however indicates that it has been less affected by the cluster wind of Westerlund 1 (W20 and W26 have pronounced cometary shaped nebulae).

One reason for the dissent is that often it may not be possible to determine the formation process. For example, a planet formed by accretion around a star may get ejected from the system to become free-floating, and likewise a sub-brown dwarf that formed on its own in a star cluster through cloud collapse may get captured into orbit around a star. One study suggests that objects above formed through gravitational instability and should not be thought of as planets. The 13 Jupiter-mass cutoff represents an average mass rather than a precise threshold value.

Although very luminous, WR 25 is beyond naked-eye visibility due to heavy dust extinction of clouds in the nebula, and because much of the emitted radiation is in the ultraviolet. It has been observed in X-rays and infra-red. WR 25 lies at the western limit of the Trumpler 16 star cluster, part of Carina OB1, one of the largest stellar associations in the Milky Way Galaxy. Because of its extreme luminosity it greatly affects its stellar environment, seen in the thin long arcs and filaments moving away from the star, including the Finger Nebula.

The Order was instituted not later than 1955 by the last Shah of Iran, Mohammad Reza Pahlavi. In 1959-67 it consisted of two, and since 1967 - of three classes (1st class, 2nd class, and 3rd class), and was awarded to female persons of high status, for deserving special recognition or conspicuous appreciation by the Shah. It is believed that the Order honours Soraya Esfandiary-Bakhtiari, the second wife of the former Shah Mohammad Reza Pahlavi. The name of the order refers to the Pleiades, a star cluster located in the constellation Taurus in the northern hemisphere.

The Alastor Cluster is the fictional setting of three of American writer Jack Vance's novels: Trullion: Alastor 2262, Marune: Alastor 933, and Wyst: Alastor 1716, each named after a world in the cluster. Vance planned a fourth novel Pharism: Alastor 458, but it was never written. A globular star cluster Vance describes as "a whorl of thirty thousand live stars in an irregular volume twenty to thirty light-years in diameter," the Alastor Cluster is part of Vance's larger Gaean Reach fictional universe. Three thousand of the star systems in the cluster are inhabited by five trillion humans.

Uncertainties have diminished over the years, due in part to discoveries such as RS Puppis. Delta Cephei is also of particular importance as a calibrator of the Cepheid period-luminosity relation since its distance is among the most precisely established for a Cepheid, partly because it is a member of a star cluster and the availability of precise Hubble Space Telescope/Hipparcos parallaxes. The accuracy of the distance measurements to Cepheid variables and other bodies within 7,500 lightyears is vastly improved by combining images from Hubble taken six months apart when the Earth and Hubble are on opposite sides of the Sun.

Parallax measurements have been used to determine the distance to some of the stars clusters thought to be related to the Serpens-Aquila Rift. The distances to both W40 and Serpens-South were measured to be 436±9 pc (1420±30 light-years) using astrometric measurements of several cluster members observed with the Very Long Baseline Array (VLBA). For radio sources the Serpens Main star cluster, parallax measurements from the VLBA give a distance of 415±15 pc. The similarity in distance is consistent with the idea that these discrete star-forming regions are part of the same star- forming complex.

They are often considered a pest on both busy lizzie (Impatiens wallerana) and fuchsias (Fuchsia sp.). Caterpillars of this species have also been seen feeding on arum lily (Zantedeschia aethiopica), Argentine trumpet vine (Clytostoma callistegioides), climbing guinea flower (Hibbertia scandens), billy goat plum (Planchonia careya), godetia (Clarkia amoena), star cluster (Pentas lanceolata), Australian native violet (Viola hederacea) and slender grape (Cayratia clematidea). The larvae are black with yellow dots, they have a small spine on their tails and use it as a mimicked head. Before pupating the caterpillar will reach a length of about 70 mm.

The alt=The Pleiades star cluster Author Graham Hancock, in his book Fingerprints of the Gods, interpreted Coe's remarks in Breaking the Maya Code as evidence for the prophecy of a global cataclysm. Filmmaker Roland Emmerich later credited the book with inspiring his 2009 disaster film 2012. Other speculations regarding doomsday in 2012 included predictions by the Web Bot project, a computer program that purports to predict the future by analyzing Internet chatter. However, commentators have rejected claims that the bot is able to predict natural disasters, as opposed to human-caused disasters like stock market crashes.

Rice attended the University of Pittsburgh where she was awarded two B.A. degrees, one in Physics & Astronomy, and the other in German. Following her graduation from the University of Pittsburgh, she then moved to Los Angeles where she completed her M.S. and her Ph.D. at the University of California, Los Angeles. Her master's thesis centered around the characterization of stars within the a young star cluster in the constellation of Aquila. The results of her thesis, which relied upon high-resolution spectra obtained by Lisa Prato, were published in the Astrophysical Journal in 2006 and in the upcoming Handbook of Star Forming Regions.

However, most have been observed in farther regions of the universe. In the galaxy M82 alone, 197 young SSCs have been observed and identified using the Hubble Space Telescope. Generally, SSCs have been seen to form in the interactions between galaxies and in regions of high amounts of star formation with high enough pressures to satisfy the properties needed for the formation of a star cluster. These regions can include newer galaxies with much new star formation, dwarf starburst galaxies, arms of a spiral galaxy that have a high star formation rate, and in the merging of galaxies.

Upsilon Tauri (υ Tauri) is a solitary, white-hued star in the zodiac constellation of Taurus, and is a member of the Hyades star cluster. It is faintly visible to the naked eye with an apparent visual magnitude of +4.28. Based upon an annual parallax shift of 21.21 mas seen from Earth, it is around 154 light years from the Sun. This is an A-type main sequence star with a stellar classification of A8 Vn. It is classified as a Delta Scuti type variable star and its brightness varies from magnitude +4.28 to +4.31 with a period of 3.56 hours.

WOH G64 was discovered in the 1970s by Bengt Westerlund, Olander and Hedin. Like NML Cygni, the "WOH" in the star's name comes from the names of its three discoverers, but in this case refers to a whole catalogue of giant and supergiant stars in the LMC. Westerlund also discovered another notable red supergiant star, Westerlund 1-26, found in the massive super star cluster Westerlund 1 in the constellation Ara. In 1986, infrared observations showed that it was a highly luminous supergiant surrounded by gas and dust which absorbed around three quarters of its radiation.

One of the most massive stars known is Eta Carinae, with ; its lifespan is very short—only several million years at most. A study of the Arches Cluster suggests that is the upper limit for stars in the current era of the universe. The reason for this limit is not precisely known, but it is partially due to the Eddington luminosity which defines the maximum amount of luminosity that can pass through the atmosphere of a star without ejecting the gases into space. However, a star named R136a1 in the RMC 136a star cluster has been measured at 315 , putting this limit into question.

R136 (formally known as RMC 136 from the Radcliffe Observatory Magellanic Clouds catalogue) is the central concentration of stars in the NGC 2070 star cluster, which lies at the centre of the Tarantula Nebula in the Large Magellanic Cloud. When originally named it was an unresolved stellar object (catalogued as HD 38268 and Wolf-Rayet star Brey 82) but is now known to include 72 class O and Wolf–Rayet stars within 5 parsecs (20 arc seconds) of the centre of the cluster. The extreme number and concentration of young massive stars in this part of the LMC qualifies it as a starburst region.

The number of stars that remain bound to the SMBH after the kick depends both on , and on how densely the stars were clustered about the SMBH before the kick. A number of arguments suggest that the total stellar mass would be roughly 0.1% of the mass of the SMBH or less. The biggest HCSSs would carry perhaps a few million stars, making them comparable in luminosity to a globular cluster or ultra-compact dwarf galaxy. Aside from being very compact, the main difference between an HCSS and an ordinary star cluster is the much greater mass of the HCSS, due to the SMBH at its centre.

First noticed in 1991, it is thought to be a cannonball star, shot out of a star cluster and now moving rapidly through space directly away from the galactic disc. The WZ Sagittae-type dwarf nova DY Canis Minoris (also known as VSX J074727.6+065050) flared up to magnitude 11.4 over January and February 2008 before dropping eight magnitudes to around 19.5 over approximately 80 days. It is a remote binary star system where a white dwarf and low mass star orbit each other close enough for the former star to draw material off the latter and form an accretion disc. This material builds up until it erupts dramatically.

The age estimate can be done in two ways. Either the brown dwarf is young and still has spectral features that are associated with youth or the brown dwarf co-moves with a star or stellar group (star cluster or association), which have easier to obtain age estimates. A very young brown dwarf that was further studied with this method is 2M1207 and the companion 2M1207b. Based on the location, proper motion and spectral signature, this object was determined to belong to the ~8 million year old TW Hydrae association and the mass of the secondary was determined to be below the deuterium burning limit with 8 ± 2 .

HD 46375 is an 8th-magnitude K-type subgiant star located approximately 109 light-years away in the constellation of Monoceros. This star resembles an orange dwarf but has a larger radius and luminosity, indicating that fusion reactions in its core are starting to cease and the star is on its way becoming a red giant. The spectral type of the star is K1 IV. Its advanced evolutionary stage shows that it is considerably older than the Sun. This star has sometimes been classified as a member of the NGC 2244 star cluster in the Rosette Nebula, but in reality it just happens to lie in the foreground.

Unlike the globular clusters of the Milky Way, which show a relatively low age dispersion, Andromeda Galaxy's globular clusters have a much larger range of ages: from systems as old as the galaxy itself to much younger systems, with ages between a few hundred million years to five billion years. In 2005, astronomers discovered a completely new type of star cluster in the Andromeda Galaxy. The new-found clusters contain hundreds of thousands of stars, a similar number of stars that can be found in globular clusters. What distinguishes them from the globular clusters is that they are much larger—several hundred light-years across—and hundreds of times less dense.

In Chinese, (), meaning Willow, refers to an asterism consisting of ρ Hydrae, δ Hydra, σ Hydrae, η Hydrae, ε Hydrae, ζ Hydrae, ω Hydrae and θ Hydrae 中國星座神話, written by 陳久金. Published by 台灣書房出版有限公司, 2005, . Consequently, ρ Hydrae itself is known as (, ). AEEA (Activities of Exhibition and Education in Astronomy) 天文教育資訊網 2006 年 5 月 28 日 The people of Groote Eylandt called Unwala, "The Crab", for the star cluster including this star, δ Hya (Lisan al Sudja), ε Hya, η Hya, ζ Hya and σ Hya (Minchir).

In Turkish the Pleiades are known as Ülker. According to the Middle Turkic lexicographer Kaşgarlı Mahmud, writing in the 11th century, ülker çerig refers to a military ambush (çerig meaning 'troops in battle formation'): "The army is broken up into detachments posted in various places," and when one detachment falls back the others follow after it, and by this device "(the enemy) is often routed." Thus ülker çerig literally means 'an army made up of a group of detachments', which forms an apt simile for a star cluster. Ülker is also a unisex given name, a surname and the name of a food company best known for its chocolates.

The Ojibwa (Chippewa) Native Americans call this constellation Kabibona'kan, the Winter Maker, as its presence in the night sky heralds winter. To the Lakota Native Americans, Tayamnicankhu (Orion's Belt) is the spine of a bison. The great rectangle of Orion is the bison's ribs; the Pleiades star cluster in nearby Taurus is the bison's head; and Sirius in Canis Major, known as Tayamnisinte, is its tail. Another Lakota myth mentions that the bottom half of Orion, the Constellation of the Hand, represented the arm of a chief that was ripped off by the Thunder People as a punishment from the gods for his selfishness.

The distance of Westerlund 1-237 is assumed to be around or based on it being commonly thought of as a member of the Westerlund 1 star cluster (the elliptical shape of its nebula indicates that it might not be near the center of W1, while other RSGs like W20 and W26 are). Another source suggests a similar distance of . Westerlund's 1987 analysis assigned a spectral type of M6+ III to W1-237 and considered it to be a foreground giant with a luminosity only around . Gaia Data Release 2 gives a parallax of for W1-237, implying a distance of and a luminosity of with a corresponding radius of .

The sash badge of the first class is a round medallion made of gold gilt surrounded by six open ornaments, shaped as large double loops in gold; with between the ornaments partly white enameled, small shell-shaped designs. The central disc is made of blue enamel, with placed on it seven golden stars, topped with brilliants, and depicting the star cluster Pleiades. Furthermore, the disc itself is surrounded by a white enamel and gold edged ring with twenty-four stars thereon, made of gold and brilliants. The disc is topped by a stylized imperial Pahlavi Crown, enameled in different colors and enriched with carbuncles and brilliants.

There is some evidence that the technique has been known since ancient times, as it seems to have been reported by Aristotle while observing the star cluster now known as M41.M41 possibly recorded by Aristotle This technique of being able to see very dim lights over a long distance has also been passed down over hundreds of generations of sailors whose duties included standing lookout watches, making one better able to spot dim lights from other ships or shore locations at night. It also matters whether you avert right or left. The most effective direction is that which places the object on the nasal side of the vision.

A bow shock is being formed where the stellar wind is colliding with the surrounding interstellar medium. The peculiar velocity of Delta Cephei is relative to its neighbors. It is a suspected member of the Cep OB6 star cluster, and hence may be around the same age as the cluster: around 79 million years. At an angular separation of 40 arc seconds from Delta Cephei is a 7.5 magnitude companion star with the identifier HD 213307, called component C in multiple star catalogues, which is visible in small telescopes. HD 213307 itself is a binary star system with a combined stellar classification of B7-8 III-IV.

Gamma Tauri (γ Tauri, abbreviated Gamma Tau, γ Tau) is either a solitary, binary or double star (the Washington Double Star Catalog notes it as a "Dubious Double" or "Bogus Binary") that marks the tip of the "V" in the constellation of Taurus. It is a member of, and located within about 2.5 parsecs of the center of, the Hyades star cluster, the nearest open cluster to the Sun. Based upon parallax measurements, Gamma Tauri is approximately 154 light-years from the Sun. Considered as a pair of stars, the two components are designated Gamma Tauri A (officially named Prima Hyadum , the traditional name for the system) and B.

The Serpens South star cluster is a relatively dense group of more than 600 young stars, dozens of which are protostars just beginning to form. The cluster is situated in the southern portion of the Serpens cloud (adjacent to the star-forming region known as W40). The stars are embedded in a dense filament of interstellar gas, which is part of the giant molecular cloud that has given rise to the cluster of young stars in W40. This entire complex is located at a distance of 1420 light-years (436 pc) from the Earth, and is approximately the same distance as the Serpens Main cluster.

The forward-moving narrative stream deals with the attempts of Diziet Sma and a drone named Skaffen-Amtiskaw (of Special Circumstances, a division of Contact) to re-enlist Zakalwe for another job. He must make contact with Beychae, an old colleague, who lives in a politically unstable star cluster, to further the aims of the Culture in the region. The payment that Zakalwe demands is the location of a woman, named Livueta. The backward-moving narrative stream describes earlier jobs that Zakalwe has performed for the Culture, ultimately returning to his pre-Culture childhood with his two sisters (Livueta and Darckense) and a boy his age named Elethiomel whose father has been imprisoned for treason.

In the end, supernova explosions and strong stellar winds from the most massive stars in the resulting star cluster will disperse the gases of the H II region, leaving behind a cluster of stars which have formed, such as the Pleiades. H II regions can be observed at considerable distances in the universe, and the study of extragalactic H II regions is important in determining the distance and chemical composition of galaxies. Spiral and irregular galaxies contain many H II regions, while elliptical galaxies are almost devoid of them. In spiral galaxies, including our Milky Way, H II regions are concentrated in the spiral arms, while in irregular galaxies they are distributed chaotically.

H-band infrared image of 1806-20 cluster 1806-20 (originally named the SGR 1806-20 cluster) is a heavily obscured star cluster on the far side of the Milky Way, approximately 50,000 light years distant. It contains the Soft gamma repeater SGR 1806-20 and the luminous blue variable hypergiant LBV 1806-20, a candidate for the most luminous star in the Milky Way. LBV 1806-20 and many of the other massive stars in the cluster are thought likely to end as supernovas in a few million years, leaving only neutron stars or black holes as remnants. The cluster is heavily obscured by intervening dust, and mostly visible in the infrared.

Sub-brown dwarfs are formed in the manner of stars, through the collapse of a gas cloud (perhaps with the help of photo-erosion) but there is no consensus amongst astronomers on whether the formation process should be taken into account when classifying an object as a planet.What is a Planet? Debate Forces New Definition, by Robert Roy Britt, 2 November 2000 Free- floating sub-brown dwarfs can be observationally indistinguishable from rogue planets, which originally formed around a star and were ejected from orbit. Similarly, a sub-brown dwarf formed free-floating in a star cluster may be captured into orbit around a star, making distinguishing sub-brown dwarfs and large planets also difficult.

After World War I, Wallace built a small cabin in the forest near Carmel, California, which he used as a laboratory for experimenting with telepathy, which he sometimes referred to as "mental radio." He made hundreds of drawings, charts, diagrams, and writings, attempting to reveal the patterns of life, including reincarnation, communication with intelligent life on other planets, and with dead spirits. He wrote about messages from the dead, from ancient Greeks, ancient Egyptians, Vikings, and Atlanteans, to more recent dead, such as Thomas Jefferson and Charles Darwin, and transcribed messages from and drew pictures of extraterrestrial life, especially from the Pleiades star cluster. He died August 12, 1954, in Berkeley, California.

Hodge 301 (lower right) in the Tarantula Nebula Hodge 301 is a star cluster in the Tarantula Nebula, visible from Earth's Southern Hemisphere. The cluster and nebula lie about 168,000 light years away, in one of the Milky Way's orbiting satellite galaxies, the Large Magellanic Cloud. Hodge 301, along with the cluster R136, is one of two major star clusters situated in the Tarantula Nebula, a region which has seen intense bursts of star formation over the last few tens of millions of years. R136 is situated in the central regions of the nebula, while Hodge 301 is located about 150 light years away, to the north west as seen from Earth.

Possibly the oldest surviving map has been engraved on this mammoth tusk, dated to 25,000 BC, found from Pavlov in the Czech Republic. The earliest known maps are of the stars, not the earth. Dots dating to 14,500 BC found on the walls of the Lascaux caves map out part of the night sky, including the three bright stars Vega, Deneb, and Altair (the Summer Triangle asterism), as well as the Pleiades star cluster. The Cuevas de El Castillo in Spain contain a dot map of the Corona Borealis constellation dating from 12,000 BC. Cave painting and rock carvings used simple visual elements that may have aided in recognizing landscape features, such as hills or dwellings.

Certain special assumptions, such as considering that the Alpha Centauri pair may have initially formed with a wider separation and later moved closer to each other (as might be possible if they formed in a dense star cluster), would permit an accretion-friendly environment farther from the star. Bodies around Alpha Centauri A would be able to orbit at slightly farther distances due to its stronger gravity. In addition, the lack of any brown dwarfs or gas giants in close orbits around Alpha Centauri make the likelihood of terrestrial planets greater than otherwise. A theoretical study indicates that a radial velocity analysis might detect a hypothetical planet of in Alpha Centauri B's habitable zone.

Confirmation of the fact that both nuclei contain black holes was obtained by spectra from the Chandra X-ray Observatory. Astronomers estimate that the black holes will merge in another billion years. NGC 6240 also has an unusually high rate of star formation, classifying it as a starburst galaxy. This is likely due to the heat generated by the orbiting black holes and the aftermath of the collision. In 2006, a new nearby star cluster was discovered associated with the 4th magnitude star Mu Ophiuchi. The Mamajek 2 cluster appears to be a poor cluster remnant analogous to the Ursa Major Moving Group, but 7 times more distant (approximately 170 parsecs away).

In 2011, a team of researchers studied the non- thermal emission of the galaxy center and indicated that the source strengths of radio waves are too strong to come from x-ray binaries while the source strengths of x-rays are too strong to be supernova remnants. However, these sources do align with known data for black holes. This original paper postulated the mass of the black hole to be ~, but a newer study has refined the estimate to . The presence of SSCs near the center of the galaxy, and not a singular nuclear star cluster (NSC) has led some to believe that Hen 2-10 is a galaxy in its early years.

He remained in Tartu until he retired in 1865, and then returned to Germany. By examining the proper motions of stars, he came up with his "Central Sun Hypothesis", according to which the center of the galaxy was located in the Pleiades star cluster and that the Sun revolves around it. He got the location wrong. He published many scientific works, among them a two-volume History of Descriptive Astronomy in 1873. In 1864, he proposed a calendar reform for Russia: After dropping 12 days to align with Gregorian calendar dates before the year 1900, the leap year in 1900 along with every 128th year afterwards (2028, 2156, etc.) under the Julian rules would be cancelled.

A super star cluster (SSC) is a very massive young open cluster that is thought to be the precursor of a globular cluster. These clusters are referred to as "super" due to the fact that they are relatively more luminous and contain more mass than other young star clusters. The SSC, however, does not have to physically be larger than other clusters of lower mass and luminosity. They typically contain a very large number of young, massive stars that ionize a surrounding HII region or a so-called "Ultra dense HII regions (UDHIIs)" in the Milky Way Galaxy as well as in other galaxies (however, SSCs do not always have to be inside an HII region).

The 'particles' treated by the simulation may or may not correspond to physical objects which are particulate in nature. For example, an N-body simulation of a star cluster might have a particle per star, so each particle has some physical significance. On the other hand, a simulation of a gas cloud cannot afford to have a particle for each atom or molecule of gas as this would require on the order of particles for each mole of material (see Avogadro constant), so a single 'particle' would represent some much larger quantity of gas (often implemented using Smoothed Particle Hydrodynamics). This quantity need not have any physical significance, but must be chosen as a compromise between accuracy and manageable computer requirements.

Despite its proximity to the solar system and the solid angle that it consequently covers, the stream contains only a few hundred thousand stars. The low surface brightness of the galaxy (possibly as low as 32.5 mag/arcmin²) may have militated against its detection in surveys before SDSS. The number of stars in the stream is not greatly in excess of a star cluster, and it has been described by a member of the team that discovered it as "a rather pathetic galaxy" in comparison to the Milky Way. Many of the stars have been known for centuries and thought of as normal Milky Way stars, although they have a lower metallicity than normal Population I stars in the Milky Way.

Artist's conception of a magnetar, with magnetic field lines Artist's conception of a powerful magnetar in a star cluster A magnetar is a type of neutron star believed to have an extremely powerful magnetic field (∼109 to 1011 T, ∼1013 to 1015 G). The magnetic field decay powers the emission of high-energy electromagnetic radiation, particularly X-rays and gamma rays.Ward; Brownlee, p.286 The theory regarding these objects was proposed by Robert Duncan and Christopher Thompson in 1992, but the first recorded burst of gamma rays thought to have been from a magnetar had been detected on March 5, 1979. During the following decade, the magnetar hypothesis became widely accepted as a likely explanation for soft gamma repeaters (SGRs) and anomalous X-ray pulsars (AXPs).

The sednoids' orbits cannot be explained by perturbations from the giant planets, nor by interaction with the galactic tides. If they formed in their current locations, their orbits must originally have been circular; otherwise accretion (the coalescence of smaller bodies into larger ones) would not have been possible because the large relative velocities between planetesimals would have been too disruptive. Their present elliptical orbits can be explained by several hypotheses: # These objects could have had their orbits and perihelion distances "lifted" by the passage of a nearby star when the Sun was still embedded in its birth star cluster. # Their orbits could have been disrupted by an as-yet-unknown planet-sized body beyond the Kuiper belt such as the hypothesized Planet Nine.

Iota Herculis is a B-type subgiant star that is at the end of its hydrogen fusion stage. With a stellar classification B3IV, it is considerably larger than the Sun, having a mass that is 6.5 times solar and a radius 5.3 times. Though its apparent magnitude is only 3.80, it is 2,500 times more luminous than the Sun, yielding an absolute magnitude of -2.11, brighter in fact than the most of the hot B stars in the Pleiades open star cluster. The Hipparcos satellite mission estimated its distance at roughly 152 parsecs (pc) from Earth, or 496 light years (ly) away; an updated parallax measurement from Floor van Leeuwen in 2007, however, puts the distance at 455ly with a much tighter error factor of only 8ly.

The Pleiades (, ), also known as the Seven Sisters and Messier 45, are an open star cluster containing middle-aged, hot B-type stars in the north-west of the constellation Taurus. It is among the star clusters nearest to Earth, it is the nearest Messier object to Earth, and is the cluster most obvious to the naked eye in the night sky. The cluster is dominated by hot blue and luminous stars that have formed within the last 100 million years. Reflection nebulae around the brightest stars were once thought to be left over material from the formation of the cluster, but are now considered likely to be an unrelated dust cloud in the interstellar medium through which the stars are currently passing.

Star cluster Pismis 24 with a nebula One of the oldest fields in astronomy, and in all of science, is the measurement of the positions of celestial objects. Historically, accurate knowledge of the positions of the Sun, Moon, planets and stars has been essential in celestial navigation (the use of celestial objects to guide navigation) and in the making of calendars. Careful measurement of the positions of the planets has led to a solid understanding of gravitational perturbations, and an ability to determine past and future positions of the planets with great accuracy, a field known as celestial mechanics. More recently the tracking of near-Earth objects will allow for predictions of close encounters or potential collisions of the Earth with those objects.

The star cluster was important for navigation and timing the seasons. The first rising of the Pleiades and of Rigel (Puanga in northern Māori, Puaka in southern Māori) occurs just prior to sunrise in late May or early June. The actual time for the celebration of Matariki varies, some iwi (tribe or clan) celebrate it immediately, others wait until the rising of the next full moon, or the dawn of the next new moon—and others use the rising of Puanga/Puaka (Rigel) in a similar way."Stars are set for a happy Maori New Year" , Tariana Turia on the Maori Party website In traditional times, Matariki was a season to celebrate and to prepare the ground for the coming year.

The lone exception is the BRZ, introduced in 2012 via a partnership with Toyota, which pairs the boxer engine with rear-wheel-drive. Subaru also offers turbocharged versions of their passenger cars, such as the WRX, Legacy and Outback XT, Ascent, and formerly the Legacy GT and Forester XT. In Western markets, Subaru vehicles have traditionally attracted a small but devoted core of buyers. The company's marketing targets those who desire its signature engine and drive train, all-wheel drive and rough-road capabilities, or affordable sports car designs. Subaru is the Japanese name for the Pleiades star cluster M45, or the "Seven Sisters" (one of whom tradition says is invisible – hence only six stars in the Subaru logo), which in turn inspires the logo and alludes to the companies that merged to create FHI.

Westerlund 1 (abbreviated Wd1, sometimes called Ara Cluster) is a compact young super star cluster in the Milky Way galaxy, about 3.2 kpc away from Earth. It is one of the most massive young star clusters in the Milky Way, and was discovered by Bengt Westerlund in 1961 but remained largely unstudied for many years due to high interstellar absorption in its direction. In the future, it will probably evolve into a globular cluster. The cluster contains a large number of rare, evolved, high-mass stars, including: 6 yellow hypergiants, 4 red supergiants including Westerlund 1-26, one of the largest known stars, 24 Wolf-Rayet stars, a luminous blue variable, many OB supergiants, and an unusual supergiant sgB[e] star which has been proposed to be the remnant of a recent stellar merger.

In the year 3000 Earth has become a toxic dump ravaged by careless humans, leaving an uninhabitable, polluted wasteland. The powerful alien space pirates Gulfer, led by the evil Queen ZZ Badnusty, plan to harvest the pollution to create weapons of mass destruction. The United Star Cluster of Leezaluth sent a warning to Earth about their plans, stating that if they could not stop them, Leezaluth would be forced to supernova Earth's sun to avoid war with Gulfer; but if humans succeeded, Leezaluth would use their technology to restore Earth to its former beauty. Legendary space hero Dan Dare (Diaz in the Japanese original), a young but brave and very skilled ace pilot from Earth was chosen to be the pilot of a new starfighter to combat Gulfer.

The irregular variable star Z Sagittae is a member of this cluster. M71 was long thought (until the 1970s) to be a densely packed open cluster and was classified as such by leading astronomers in the field of star cluster research due to its lacking a dense central compression, and to its stars having more "metals" than is usual for an ancient globular cluster; furthermore, it lacks the RR Lyrae "cluster" variable stars that are common in most globulars. However, modern photometric photometry has detected a short "horizontal branch" in the H-R diagram of M71, which is characteristic of a globular cluster. The shortness of the branch explains the lacking of the RR Lyrae variables and is due to the globular's relatively young age of 9-10 billion years.

RCW 36 (also designated Gum 20) is an emission nebula containing an open cluster in the constellation Vela. This H II region is part of a larger-scale star-forming complex known as the Vela Molecular Ridge (VMR), a collection of molecular clouds in the Milky Way that contain multiple sites of ongoing star- formation activity. The VMR is made up of several distinct clouds, and RCW 36 is embedded in the VMR Cloud C. RCW 36 is one of the sites of massive-star formation closest to our Solar System, whose distance of approximately 700 parsecs (2300 light-years). The most massive stars in the star cluster are two stars with late-O or early-B spectral types, but the cluster also contains hundreds of lower-mass stars.

When observed in the ultraviolet and mid-infrared, the central region and bar of show old stars and low rates of star formation, with rates increasing along the spiral arms as distance from the core increases. The most active region of star formation, located in the northeast arm, shows a stellar flux around 1,000 times higher than in the central region, though this may be affected by the density of stellar dust in the core. The extended portions of both arms exhibit young star cluster formations with ages ranging from one to one hundred million years. Star formation rates in the northeast extended arm are twice that of the southwest extended arm, and five times the formation rate in the sections of the arms closer to the central region.

Spencer was back in the saddle on 20 May when Red Evie started favourite for a seven furlong handicap at Newbury Racecourse and won "easily" from fifteen opponents. She returned to the track ten days later for a minor race over seven furlongs at Leicester Racecourse in which she started odds-on favourite and won "comfortably" by a length and a half from the Henry Cecil-trained Star Cluster, having taken the lead two furlongs out. Red Evie contested her most important race up to that time at Royal Ascot when she contested the Listed Sandringham Handicap, a race in which she was assigned a weight of 124 pounds. She was one of three co-favourites on 5/1 alongside La Mottie and Makderah in a field of nineteen fillies.

NGC 206 is the richest and most conspicuous star cloud in the Andromeda Galaxy as well as one of the largest and brightest star formation regions of the Local Group. It contains more than 300 stars brighter than Mb=−3.6. It was originally identified by Edwin Hubble as a star cluster but today, due to its size, it is classified as an OB association. NGC 206 is located in a spiral arm of the Andromeda Galaxy, in a zone free of neutral hydrogen and has a double structure, with one region that has an age of around 10 million years and includes several H II regions in one of its borders and other with an age of between 40 million years and 50 million years that includes a number of cepheids.

Modern observational versions of the chart replace spectral type by a color index (in diagrams made in the middle of the 20th Century, most often the B-V color) of the stars. This type of diagram is what is often called an observational Hertzsprung–Russell diagram, or specifically a color–magnitude diagram (CMD), and it is often used by observers. In cases where the stars are known to be at identical distances such as within a star cluster, a color–magnitude diagram is often used to describe the stars of the cluster with a plot in which the vertical axis is the apparent magnitude of the stars. For cluster members, by assumption there is a single additive constant difference between their apparent and absolute magnitudes, called the distance modulus, for all of that cluster of stars.

Messier 29 or M 29, also known as NGC 6913, is an open cluster of stars in the Cygnus constellation. It was discovered by Charles Messier in 1764, and can be seen from Earth by using binoculars. The star cluster is situated in the highly crowded area of Milky Way near Gamma Cygni, at a distance of 7,200 (most sources including Mallas/Kreimer and Burnham, and agreeing with early estimates or R.J. Trumpler 1930) or 4,000 light years (the latter from Kenneth Glyn Jones and the Sky Catalogue 2000.0). The Night Sky Observer's Guide by Kepple and Sanner gives a deviating value of 6,000 light years – the uncertainty due to poorly known absorption of the cluster's light. According to the Sky Catalog 2000, Messier 29 is included in the Cygnus OB1 association, and is approaching us at 28 km/s.

Heggie has conducted pioneering theoretical research on the topic of the classical gravitational N-body problem, with a particular focus on the three- body problem, and related applications to the dynamical evolution of globular star clusters and high-performance computing. The article in which he presented the theory of binary evolution in stellar dynamics (often referred to as Heggie's law) has found an outstanding spectrum of applications in many astrophysical domains. One of the originators of the current paradigm of the dynamical evolution of collisional stellar systems, he has made seminal contributions also to the quantitative study of prehistoric mathematics and astronomy. On these subjects, he has authored or co-authored of two books: The Gravitational Million-Body Problem: A Multidisciplinary Approach to Star Cluster Dynamics and Megalithic Science: Ancient Mathematics and Astronomy in North-west Europe.

Artist's impression of the magnetar CXOU J164710.2-455216 in the star cluster Westerlund 1 The age of Wd1 is estimated at 4–5 Myr from comparison of the population of evolved stars with models of stellar evolution. The presence of significant numbers of both Wolf–Rayet stars and red and yellow supergiants in Wd1 represents a strong constraint on the age: theory suggests that red supergiants will not form until around 4 Myr as the most massive stars do not go through a red supergiant phase, while the Wolf–Rayet population declines sharply after 5 Myr. This range of ages is broadly consistent with infra-red observations of Wd1 that reveal the presence of late-O main sequence stars, although a lower age of around 3.5 Myr has been suggested from observations of lower-mass stars in Wd1. Comet-like stars in Westerlund 1.

Later products added minor one-hex and zero-hex (on the strategic galactic game map) races such as the WYN star cluster, the Jindarians, the Seltorians, and the Lyran Democratic Republic. The Orion Pirates, originally presented as a monolithic quasi- corporate entity home-based within the Orion Enclave inside Federation territory, were further differentiated into various "clans" or branches operating out of various territories scattered among all the major races of the Octant. There were also further reinforcements added to the Tholians and the Andromedan Invaders from their extragalactic places of origin (the Neo- Tholian ships and new Andromedan ship and base classes). It is useful to visualize the Alpha Octant as a circular clock face representing the Federation, the largest territory here. Conceived thus, the Kzinti Hegemony would border the Federation's "west" edge along the clock's circumference between the 10 o'clock and 11:30 o'clock positions.

According to a 1971 NASA technical memorandum, Min al Azʽal or Minazal were the title for five stars: Delta Hydrae as Minazal I, Eta Hydrae as Minazal II, Epsilon Hydrae as Minazal III, Rho Hydrae as Minazal IV and Zeta Hydrae as Minazal V.

Elson did her postdoctoral work at the Institute for Advanced Study under the supervision of John N. Bahcall, continuing her star cluster work using ground-based telescopes when plans to use the new capabilities of the Hubble space telescope were affected by its delayed launch following the Challenger space shuttle disaster. In 1987, she was the first-named author on a major review article on star clusters for the Annual Review of Astronomy and Astrophysics, after which she took up a Bunting Fellowship at Radcliffe College in 1989, where she taught creative writing, followed by a term teaching a Harvard expository writing course on science and ethics. In 1989 she was the youngest astronomer selected to serve on a US National Academy of Sciences decennial review of the field. In the early 1990s she returned to the Institute of Astronomy at Cambridge to accept the research position she would hold for the remainder of her life.

Sacred Books of the East, Vols. 12, 26, 24, 37, 47, translated by Julius Eggeling [published between 1882 and 1900] B. N. Narahari Achar also notes several other estimations, such as that of S.B. Dixit, D. Pingree, and N. Achar, in relation to a statement in the text that the Krittikas (the open star cluster Pleiades) never deviate from the east; Dixit's interpretation of this statement to mean that the Krittikas rise exactly in the east, and calculated that the Krittikas were on the celestial equator at about 3000 BCE, is a subject of debate between the named scholars; Pingree rejects Dixit’s arguments. S.C. Kak states that a 'conservative chronology places the final form of the Satapatha Brahmana to 1000-800 B.C.E... [although on] the other hand, it is accepted that the events described in the Vedas and the Brahmanas deal with astronomical events of the 4th millennium [i.e. 3,000] B.C.E. and earlier'.

This star- forming region is located in the 5-kpc ring, a ring with that radius that encircles the central bar of our galaxy and that contains most of its molecular hydrogen as well as most of its star formation. It is associated with a very massive complex of molecular clouds with a total mass of more than 7 million times the one of our Sun and is forming stars of all masses within star clusters that are less massive versions of those found on starburst galaxies; it still has capacity to form more clusters. There are also massive protostars as well as stellar clusters in formation embedded within the nebula, with this star formation region likened to NGC 3603 W43's center, finally, contains a dense and massive star cluster with several O stars and Wolf-Rayet stars that has been compared due to its compactness to NGC 3603 or even Large Magellanic Cloud's R136.

Using the Hubble Space Telescope, Figer observed approximately one thousand stars in a young star cluster, the Arches Cluster, which is near the Galactic center. By measuring the initial mass function, he identified an upper limit of 150 solar masses to the masses of stars. Figer, D. F. 2005, An upper limit to the masses of stars, Nature, 34, 192 Figer led a team to identify the Pistol star as one of the most massive stars known in the Galaxy using data that the team obtained using the Hubble Space Telescope.Figer, D. F., Najarro, F., Morris, M., McLean, I. S., Geballe, T. R., Ghez, A. M., & Langer, N. 1998, The Pistol Star, Astrophysical Journal, 506, 384 His teams performed the first census of massive stars in both the Quintuplet Cluster and the Arches Cluster, finding that massive star clusters form in the present-day Galaxy, as opposed to the previous paradigm that suggested such clusters only formed at the time that the Galaxy formed.

Delta Cancri was involved in the first recorded occultation by Jupiter: Delta Cancri also marks the famous open star cluster Praesepe (or the Beehive Cluster, also known as Messier 44). In ancient times M44 was used as a weather gauge as the following Greek rhyme from Aratos' Prognostica reveals: The meaning of this verse is that if Asellus Borealis or Gamma CancrisKaler, 2009: is hidden by clouds, the wind will be from the south and that situation will be reversed if Asellus Australis is obscured. There is some doubt however as to the accuracy of this as Allen notes: "Our modern Weather Bureau would probably tell us that if one of these stars were thus concealed, the other also would be." (Allen, 1898) But Delta Cancri also acts as more than just a dubious weather guide: it is a reliable signpost for finding the vividly red star X Cancri as Patrick Moore notes in his guidebook Stars of the Southern Skies: Delta Cancri also marks the radiant of the Delta Cancrids meteor shower.

Anatomy of a Pleiades node, shown on display at the NASA Ames Exploration Center, in Mountain View, California Built in 2008 and named for the Pleiades open star cluster, the supercomputer debuted as the third most powerful supercomputer in the world at 487 teraflops. It originally contained 100 SGI Altix ICE 8200EX racks with 12,800 Intel Xeon quad-core E5472 Harpertown processors connected with more than 20 miles of InfiniBand double data rate (DDR) cabling. With the addition of ten more racks of quad-core X5570 Nehalem processors in 2009, Pleiades ranked sixth on the November 2009 TOP500 with 14,080 processors running at 544 teraflops. In January 2010, the scientists and engineers at NAS successfully completed a "live integration" of another ICE 8200 rack by connecting the new rack's InfiniBand dual port fabric via 44 fibre cables while the supercomputer was still running a full workload, saving 2 million hours in productivity that would otherwise have been lost. Another expansion in 2010 added 32 new SGI Altix ICE 8400 racks with Intel Xeon six-core X5670 Westmere processors, bringing up to 18,432 processors (81,920 cores in 144 racks) at a theoretical peak of 973 teraflops and a LINPACK rating of 773 teraflops.
