Three supernovae have been observed in the Whirlpool Galaxy: In 1994, SN 1994I was observed in the Whirlpool Galaxy. It was classified as type Ic, indicating that its progenitor star was very massive and had already shed much of its mass, and its brightness peaked at apparent magnitude 12.91. In June 2005 the type II supernova SN 2005cs was observed in the Whirlpool Galaxy, peaking at apparent magnitude 14. On 31 May 2011 a type II supernova was detected in the Whirlpool Galaxy, peaking at magnitude 12.1.

Like stars, most galaxies do not have names. There are a few exceptions such as the Andromeda Galaxy, the Whirlpool Galaxy, and others, but most simply have a catalog number. In the 19th century, the exact nature of galaxies was not yet understood, and the early catalogs simply grouped together open clusters, globular clusters, nebulas, and galaxies: the Messier catalog has 110 in total. The Andromeda Galaxy is Messier object 31, or M31; the Whirlpool Galaxy is M51.

After a week of more data being collected, consensus grew among observers that SN 1994I was a Type Ic. By chance, observations of SN 1994I were obtained before its discovery was reported. High school students Heather Tartara and Melody Spence requested observations of the Whirlpool Galaxy on March 29 and 31, 1994. Their request was made through the Hands-On Universe program, which allows elementary and high school students to request observations on automated telescopes. Their images captured the Whirlpool Galaxy just before and after SN 1994I began to brighten, and are some of the earliest data recorded for a supernova.

Drawing of the Whirlpool Galaxy by Rosse in 1845 Lord Rosse performed astronomical studies and discovered the spiral nature of some nebulas, today known to be spiral galaxies. Rosse's telescope Leviathan was the first to reveal the spiral structure of M51, a galaxy nicknamed later as the "Whirlpool Galaxy", and his drawings of it closely resemble modern photographs. Rosse named the Crab Nebula, based on an earlier drawing made with his older 36-inch (91 cm) telescope in which it resembled a crab. A few years later, when the 72-inch (183 cm) telescope was in service, he produced an improved drawing of considerably different appearance, but the original name continued to be used.

As a consequence of the gravitational interaction with the Whirlpool Galaxy, NGC 5195 is highly distorted. Classification of its morphology is difficult, as it is sometimes identified as a lenticular galaxy or as an amorphous or irregular galaxy. It has been described as falling outside the standard morphological classification system.

Strings of red H II regions delineate the arms of the Whirlpool Galaxy. H II regions are found only in spiral galaxies like the Milky Way and irregular galaxies. They are not seen in elliptical galaxies. In irregular galaxies, they may be dispersed throughout the galaxy, but in spirals they are most abundant within the spiral arms.

M63 is part of the M51 Group, a group of galaxies that also includes M51 (the 'Whirlpool Galaxy'). In 1971, a supernova with a magnitude of 11.8 appeared in one of the arms of M63. It was discovered May 24, 1971 and reached peak light around May 26. The spectrum of is consistent with a supernova of type I. However, the spectroscopic behavior appeared anomalous.

NGC 5195 and the Whirlpool Galaxy compose one of the most noted interacting galaxy pairs in astronomy. The two galaxies are listed in the Atlas of Peculiar Galaxies as one of several prominent examples of a spiral galaxy with a companion galaxy. The system was also the subject of very early theoretical investigations into galaxy interactions. The two galaxies are connected by a dust-rich tidal bridge.

A small number of galaxies or galaxy groups have been named after individual people. In most cases, the named individual was the person who discovered the object, who first brought attention to it, or who first studied it scientifically. Many of the brighter galaxies visible from the Northern Hemisphere have Messier numbers, named after Charles Messier. For instance, the Andromeda Galaxy is Messier 31 and the Whirlpool Galaxy is Messier 51.

The Whirlpool Galaxy is the brightest galaxy in the M51 Group, a small group of galaxies that also includes M63 (the Sunflower Galaxy), NGC 5023, and NGC 5229. This small group may actually be a subclump at the southeast end of a large, elongated group that includes the M101 Group and the NGC 5866 Group, although most group identification methods and catalogs identify the three groups as separate entities.

Her 2001 work M51 by Candlelight depicts the Whirlpool Galaxy and is included in the New Mexico History Museum's Pinhole Resource Collection. She created the image using an aluminum plate camera dotted with dozens of pinholes of varying sizes. A photograph that Bos took in Toulouse was used by graphic designer Jennifer Clark for her mural Timeless. Bos made pinhole cameras from old travel books for an exhibition at Toronto's Edward Day Gallery in 2011.

In September 2020, the detection of a candidate planet orbiting the high-mass X-ray binary M51-ULS-1 in the Whirlpool Galaxy was announced. The planet was detected by eclipses of the X-ray source, which consists of a stellar remnant (either a neutron star or a black hole) and a massive star, likely a B-type supergiant. The planet would be slightly smaller than Saturn and orbit at a distance of some tens of AU.

Similarly, many of the most well-known grand design spiral galaxies (such as the Whirlpool Galaxy) also have nearby companions. A computer simulation has shown that the dwarf companion of BX442 could have had the same effect. However, the chaotic motions of the stars in the youthful BX442 suggest that, if this is the case, the present spiral structure will not be long-lived in cosmic terms, and may have disappeared within a hundred million years or so.

Irish astronomer William Parsons, 3rd Earl of Rosse completes the first of the world's great telescopes, with a 180-cm mirror. He uses it to study and draw the structure of nebulas, and within a few months discovers the spiral structure of the Whirlpool Galaxy. French physicists Jean Foucault and Armand Fizeau take the first detailed photographs of the Sun's surface through a telescope - the birth of scientific astrophotography. Within five years, astronomers produce the first detailed photographs of the Moon.

The Whirlpool Galaxy, also known as Messier 51a, M51a, and NGC 5194, is an interacting grand-design spiral galaxy with a Seyfert 2 active galactic nucleus. It lies in the constellation Canes Venatici, and was the first galaxy to be classified as a spiral galaxy. Its distance is estimated to be 23 million light-years away from Earth. The galaxy and its companion, NGC 5195, are easily observed by amateur astronomers, and the two galaxies may be seen with binoculars.

The pronounced spiral structure of the Whirlpool Galaxy is believed to be the result of the close interaction between it and its companion galaxy NGC 5195, which may have passed through the main disk of M51 about 500 to 600 million years ago. In this proposed scenario, NGC 5195 came from behind M51 through the disk towards the observer and made another disk crossing as recently as 50 to 100 million years ago until it is where we observe it to be now, slightly behind M51.

The M51 Group, which includes the Whirlpool Galaxy (M51) and the Sunflower Galaxy (M63), is located to the southeast of the M101 Group, and the NGC 5866 Group is located to the northwest. The distances to these three groups (as determined from the distances to the individual member galaxies) are similar, which suggests that the M51 Group, the M101 Group, and the NGC 5866 Group are actually part of a single large, loose, elongated group. However, most group identification methods (including those used by the references cited above) identify these three groups as separate entities.

The four structures protect telescopes from the wind and thermal currents. The next year concrete pads in diameter were placed at random in the field, and electrical pedestals, each with six outlets, were added to power telescopes and computers. In 2009, Wi-Fi internet access was added to the Astronomy Field. The Whirlpool Galaxy (M51) in the constellation Canes Venatici, as seen from the Astronomy Field While a typical clear night might have 50 to 100 observers, each year the park hosts two major star parties which both attract several hundred astronomers for several nights.

Galaxy cluster SDSS J1152+3313. SDSS stands for Sloan Digital Sky Survey, J for Julian epoch, and 1152+3313 for the declination and right ascension respectively. Tens of thousands of galaxies have been catalogued, but only a few have well-established names, such as the Andromeda Galaxy, the Magellanic Clouds, the Whirlpool Galaxy, and the Sombrero Galaxy. Astronomers work with numbers from certain catalogues, such as the Messier catalogue, the NGC (New General Catalogue), the IC (Index Catalogue), the CGCG (Catalogue of Galaxies and of Clusters of Galaxies), the MCG (Morphological Catalogue of Galaxies) and UGC (Uppsala General Catalogue of Galaxies).

SN 1994I is a Type Ic supernova discovered on April 2, 1994 in the Whirlpool Galaxy by amateur astronomers Tim Puckett and Jerry Armstrong of the Atlanta Astronomy Club. Type Ic supernova are a rare type of supernova that result from the explosion of a very massive star that has shed its outer layers of hydrogen and helium. The explosion results in a highly luminous burst of radiation that then dims over the course of weeks or months. SN 1994I was a relatively nearby supernova, and provided an important addition to the then small collection of known Type Ic supernova.

The NGC 5866 Group is located to the northwest of both the M101 Group (which contains the Pinwheel Galaxy (M101) and its companion galaxies) and the M51 Group (which contains the Whirlpool Galaxy (M51), the Sunflower Galaxy (M63), and several other galaxies). The distances to these three groups (as determined from the distances to the individual member galaxies) are similar, which suggests that the M51 Group, the M101 Group, and the NGC 5866 Group are actually part of a large, loose, elongated structure. However, most group identification methods (including those used by the references cited above) identify these three groups as separate entities.

As of January 2020, NASA's Kepler and TESS missions had identified 4374 planetary candidates yet to be confirmed, several of them being nearly Earth-sized and located in the habitable zone, some around Sun-like stars. In September 2020, astronomers reported evidence, for the first time, of an extragalactic planet, M51-ULS-1b, detected by eclipsing a bright X-ray source (XRS), in the Whirlpool Galaxy (M51a). Also in September 2020, astronomers using microlensing techniques reported the detection, for the first time, of an earth-mass rogue planet unbounded by any star, and free floating in the Milky Way galaxy.

The Whirlpool Galaxy and its companion satellite. The Whirlpool is an unbarred spiral galaxy An unbarred spiral galaxyAstronomical Journal, "Near-infrared surface photometry and morphology in virgo cluster spiral galaxy nuclear regions", Bernard J. Rauscher, April 1995, , Astronomy Pictures, "M99" (accessed 18 April 2010) is a type of spiral galaxy without a central bar, or one that is not a barred spiral galaxy. It is designated with an SA in the galaxy morphological classification scheme. Barless spiral galaxies are one of three general types of spiral galaxies under the de Vaucouleurs system classification system, the other two being intermediate spiral galaxy and barred spiral galaxy.

Harvard astronomer Charles A. Whitney conducted his own astronomical study of The Starry Night contemporaneously with but independent of Boime (who spent almost his entire career at U.C.L.A.). While Whitney does not share Boime's certainty with regard to the constellation Aries, he concurs with Boime on the visibility of Venus in Provence at the time the painting was executed. He also sees the depiction of a spiral galaxy in the sky, although he gives credit for the original to Anglo-Irish astronomer William Parsons, Lord Rosse, whose work Flammarion reproduced. Sketch of the Whirlpool Galaxy by Lord Rosse in 1845, 44 years before Van Gogh's painting Whitney also theorizes that the swirls in the sky could represent wind, evoking the mistral that had such a profound effect on Van Gogh during the twenty-seven months he spent in Provence.

The image of the Whirlpool Galaxy in visible light (left) and infrared light (right) Located within the constellation Canes Venatici, M51 is found by following the easternmost star of the Big Dipper, Eta Ursae Majoris, and going 3.5° southwest. Its declination is +47°, making it a circumpolar for observers located above 43°N latitude; it reaches high altitudes throughout the northern hemisphere making it an accessible object from the early hours in winter through the end of spring season, after which observation is hindered in lower latitudes. M51 is visible through binoculars under dark sky conditions, and it can be resolved in detail with modern amateur telescopes. When seen through a 100 mm telescope the basic outlines of M51 (limited to 5×6') and its companion are visible. Under dark skies, and with a moderate eyepiece through a 150 mm telescope, M51's intrinsic spiral structure can be detected.
