|
|
This strong magnetic field produces incredible auroras on the planet, much like the auroras seen at Earth's poles, but on a far larger scale.
|
|
But unlike on Earth, where our auroras are produced by incoming solar particles, the auroras on Ganymede are being generated by the plasma surrounding Jupiter.
|
|
It confirms, in part, what astronomers expected, but it also shows that Jupiter's auroras behave differently than auroras on Earth — through processes that we don't fully understand yet.
|
|
Since magnetic field lines create a continuous arc between the poles, "You might imagine that what affects the auroras in the north would affect the auroras in the south," Nichols says.
|
|
While on Earth the biggest auroras are caused by solar storms — when high energy particles ejected from the Sun rain down on our planet — auroras on Jupiter are also caused by the charged particles ejected by other sources, like the planet's orbiting moon Io. The auroras also never cease and are huge, covering areas bigger than the Earth itself.

|
But there are also auroras we can't see made out of ultraviolet light, infrared light, or high-energy X-rays.
|
|
But what may be less well known is that auroras also emit X-rays, generated as the incoming particles decelerate.

Winter Wonderland by Niko Juntunen captures rich sunsets as they reflect off miles of untouched white; auroras intermingle with snow-capped trees; and bright blue nights transform into sparkling white mornings.
|
|
If it doesn't all go just right, Juno's scientific objectives—which run from examining Jupiter's auroras to gaining new insight into the birth of the solar system—are pretty much toast.
|
|
Of these four Auroras, Ms. Seo was the easiest to find fault with: In several passages, she's bland and forgettable, and her balances in the famous Rose Adagio were never secure.
|
|
He told us the average number of hairs on a square centimetre of a reindeer's back—seventeen hundred—and explained the logic behind the Kp index, a tool for predicting auroras.
|
|
If you want to try to spot the special aurora in person, NASA has a some tips for you: STEVE appears closer to the equator than where normal — often green — auroras appear.
|
|
MAVEN has already discovered that solar winds have stripped gases like oxygen and carbon dioxide from the planet, and found auroras on Mars that are similar to the northern lights on Earth.
|
|
Auroras are the signatures of a planet's magnetic field, which are thought to be key for life because they protect a planet's atmosphere from the scouring winds blowing off its nearby star.
|
|
Coronal mass ejections that are directed toward the planet can supercharge auroras at the poles or, if the solar storm is strong enough, disrupt the power grids on the planet, causing blackouts.
|
|
The huge planet in the middle of our solar system has giant Earth-sized storms, a powerful magnetic field, and extreme auroras, a series of new scientific studies published this week show.
|
|
Doeringer's covers - here of Jasper John's' earth-shaking "Flag" from 1954-1955 - are loving auroras around and part of the art and our love of it and our lives lived in it.
|
|
Scientists are particularly interested in learning more about the behavior of Jupiter's auroras now because the planet is about to get an unprecedented closeup examination, courtesy of NASA's Juno spacecraft next week.
|
|
From the ground, auroras look like beautifully colored curtains of light dancing in the sky, but from above, the northern and southern lights take on a different kind of other-worldly glow.
|
|
Space weather, auroras, comet tails, life on Earth, and the performance of our civilization's electronics are all deeply shaped by the solar wind, so it's imperative that we better understand its whims.
|
|
While JunoCam, the orbiter's optical camera, was snapping these shadowy closeups, Juno's infrared instrument JI-RAM was dutifully mapping the gas giant's infrared emissions, with particular focus on its radiant polar auroras.
|
|
A burst of hot plasma spit out by the sun is about to slam into the Earth, sparking possible auroras that could be visible in the U.S. from the Midwest to the Northeast.
|
|
Using data previously collected by the Hubble Space Telescope, and by corroborating it with Galileo's PLS data, the NASA scientists were able to characterize and pinpoint the location of the auroras on Ganymede.
|
|
The Jupiter auroras observed by NASA's Hubble Space Telescope are some of the most active and brightest ever caught by Hubble, reaching intensities over a thousand times brighter than those seen on Earth.
|
|
He sketched out a timeline of what we could expect to see from our Earth-bound perspective —from the worldwide auroras, to the breakdown of our tech, to the final return to normalcy.
|
|
Like Earth's northern and southern lights, Jupiter's auroras can be influenced by charged particles from the sun carried on the solar wind and dragged down into the planet's atmosphere along magnetic field lines.
|
|
Every year, skywatchers from all around the world venture to the Earth's poles to gaze at one of nature's most captivating events—the auroras borealis and australis, or the Northern and Southern lights.
|
|
The impact still needs to be confirmed by other astronomers, but it certainly bears the hallmarks of a meteor strike, and not something that might be produced by Jupiter's lightning flashes or auroras.
|
|
Scientists with NASA have taken a new look at the data collected during that historic encounter, providing tantalizing new details about this strange celestial object, its unique magnetic shield, and its unusually bright auroras.
|
|
Then particles from the plasma would get accelerated in the Earth's magnetic field and cause world wide auroras, as it was seen after the 1859 solar storm (which was significant smaller than a superflare).
|
|
While these particles have the potential to generate beautiful, harmless events known as auroras, they can also cause serious damage to technology, including important national assets, and be harmful to people living in space.
|
|
Our planet, by virtue of its own magnetic field, constantly deflects this bombardment; the relatively few particles that make it into Earth's atmosphere manifest themselves as glowing auroras near the North and South Poles.
|
|
Juno will get as close as 2,600 miles to Jupiter during its mission, which is primarily intended to study the planet's auroras, atmosphere, and structure, but JunoCam will be snapping photos all the way.
|
|
However, it wasn't until the early-to-mid-2000s that scientists could use satellites to observe both auroras at the same time, which allowed space physicists to clearly see that they weren't mirror images.
|
|
But they do get to witness a sunrise and sunset every hour and a half and when those intersect with special events like auroras over the north and south poles, they're ready with their cameras.
|
|
Auroras on Earth are produced by interactions between charged particles from the Sun as they enter the atmosphere, but the processes that produce the Southern and Northern Lights come in both strong and weak varieties.
|
|
This influence becomes particularly acute during geomagnetic storms, which are generally caused by coronal mass ejections—huge bubbles of magnetized plasma—and solar flares, and can lead to everything from auroras to widespread satellite failures.
|
|
The impact of chorus waves on Earth can be seen easily, depending where you are, because they are responsible for the famous northern (and southern) lights , the auroras predominantly seen from the Arctic and Antarctic.
|
|
As its mission begins, Juno will measure the strength of the solar wind around Jupiter, while Hubble sets its sights on Jupiter's auroras on a daily basis for one month, according to the Hubble statement.
|
|
Now, for the first time, astronomers say they have discovered an exoplanet by mapping the auroras of its host star, opening a new chapter in the quest to map the galactic menagerie of unseen worlds.
|
|
At least one, Dr. Seager pointed out, was as energetic as a famous solar flare called the Carrington Event in 1859, which destroyed telegraph service on Earth and sent auroras as far south as the Equator.
|
|
Also, this study shows some similarities between the Juno data and measurements taken of Earth's auroras, which to Vogt means we don't fully understand the extent to which the same physical processes are operating at both planets.
|
|
By studying rare observations of the gas giant's polar lights, scientists helmed by William Dunn and Andrew Coates at University College London found that the northern and southern auroras brightened and faded completely independently from one another.
|
|
Certain solar events like coronal mass ejections (CMEs), large blasts originating from knots in the solar magnetic field, can cause particularly bad solar storms that could paralyze power grids, endanger astronauts, and deliver strong, days-long auroras.
|
|
With Juno's orbits passing almost directly over the north and south poles, scientists can better study the powerful auroras, which are generated by charged particles traveling along Jupiter's magnetic field and colliding with molecules in the atmosphere.
|
|
Plasma eruptions from the Sun's surface — from small bursts to gigantic eruptions that can cause spectacular auroras on Earth — are all part of the same process and have the same underlying mechanism, a new study in Nature shows.
|
|
Since then, it's sent back a host of valuable data that has revealed new insights into Jupiter, like the depth of the red spot, three-dimensional views of the gas below its surface, and how its auroras work.
|
|
Scientists have been poring over the data Juno collected in its first cloud-grazingly close pass over Jupiter last August, and today published two papers on what they've discovered about Jupiter's auroras, atmosphere, and magnetic and gravity fields.
|
|
Though the resulting auroras are beautiful, the sudden rush of charged particles can interfere with electronic communications, confuse GPS, push satellites out of orbit, endanger astronauts, and even wipe out power grids if the eruption is big enough.
|
|
Juno will also beam back the highest-resolution pictures of Jupiter ever taken, once its 20-month science-gathering mission begins in earnest, showing scientists what the world's clouds and auroras look like from close range as never before.
|
|
This lovely animation explainer from Amaël Isnard shows how though we can't see magnetic forces in action, we at least get to see the auroras in the north and south poles, which reveals the invisible magnetic field of Earth.
|
|
It's happened before: Perhaps the most extreme example of a damaging solar storm occurred in 1859, when a huge CME hit Earth, lighting telegraph lines on fire and creating auroras that could be seen almost everywhere on the planet.
|
|
Auroras are a rare sight on Earth, but now, thanks to a new ultra-high definition video from NASA, people can see what it's like to be an astronaut witnessing the cosmic light show from the International Space Station.
|
|
In 1859, for instance, a CME subsequently dubbed the Carrington event, after a British astronomer who realised its connection with a powerful solar flare he had observed a few days earlier, generated auroras that could be seen in the tropics.
|
|
But initial observations show a gravitational field differing from scientist's original expectations, poles with lots of clustered storms more chaotic than Saturn's, a magnetic field twice as strong as expected, and crazy process for generating auroras, probably far different from Earth's.
|
|
If all goes well, the Parker Space Probe will deliver unprecedented insights into the dynamics of solar wind, a stream of charged particles that is responsible for everything from auroras on Earth to the destruction of the atmosphere on Mars.
|
|
Juno's goals include understanding how Jupiter formed and evolved, observing its auroras, measuring water and ammonia in the deeper atmosphere, mapping the magnetic field and looking for the evidence of a solid core at the heart of the gas giant.
|
|
If this emitted energy is aimed at the Earth, it can have a significant impact, including enhanced auroras at lower latitudes, and airline passengers can experience a higher radiation dose than usual, especially for flight paths near the Earth's poles.
|
|
They can also widespread voltage control issues, grid, grid collapse, and blown transformers, as well as auroras visible as far south as Florida and Texas, but they are rare: a probability of only four days in every 11 year cycle.
|
|
As the particles lose energy, they collide with elements in the upper atmosphere, creating shimmering bands of light in the night sky (auroras are always happening, but the Sun outshines them during the day.) CMEs are like solar wind gusts on steroids.
|
|
Jonathan Eastwood, a senior lecturer of space physics at Imperial College London who wasn't involved in the study, said the research provides interesting clues as to how planetary magnetic fields work, while also inviting us to more deeply appreciate the auroras' aesthetic charms.
|
|
In less than week, NASA's Juno mission will arrive in Jupiter's orbit for a dangerous, year-and-a-half long mission that seeks to map the gas giant's magnetic field, study its interaction with the solar wind, and determine the origin of the auroras.
|
|
Solar storms also knock out electrical systemsDuring a solar storm — when a large-scale magnetic eruption takes place on the surface of the sun, sending charged particles hurtling into space (and, if it hits Earth, often producing pretty auroras) — things get a lot more dramatic.
|
|
After ten years of puzzling over this unexpected imbalance between polar auroras, researchers led by Anders Ohma, a graduate student at the University of Bergen in Norway, think the answer could be the tilted pressure that the solar wind exerts on Earth's magnetic field.
|
|
Solar storms are triggering X-ray auroras on Jupiter that are about eight times brighter than normal over a large area of the planet and hundreds of times more energetic than Earth's "northern lights," according to a new study using data from NASA's Chandra X-ray Observatory.
|
|
A G1 watch—G for geomagnetic storm, or a disturbance of Earth's magnetosphere from solar winds, 1 for the mildest forecast—might stir up fluctuations in weak power grids, a slight disturbance in spacecraft operations, and uncommonly vivid auroras in higher altitudes like Maine and Michigan.
|
|
The best modern guess is that the Chronicle's writers were looking at an unusually powerful manifestation of the northern lights, and that the high 14C levels are a consequence of this isotope being generated abundantly in the atmosphere by elevated levels of solar radiation, which also stimulated the auroras.
|
|
"[This presents] huge challenges to our understanding of the dynamo mechanism that produces the magnetic fields in brown dwarfs and exoplanets and helps drive the auroras we see," said Gregg Hallinan, study co-author and assistant professor of astronomy at the California Institute of Astronomy, in a statement.

Citizen Scientists Discover New Feature of the Aurora BorealisIt wasn't scientists who discovered the thin, purple, east-to-west traveling glow in the northern…Read more ReadDespite these differences, scientists understandably thought that STEVEs were produced by the same processes that result in auroras, namely particle precipitation onto the ionosphere.
|
|
In this complete production, from 1991, Peter Martins includes "The Garland Dance" in Act I and adds his own touches; it's brisk, with an array of Auroras to keep it snappy, including the principals Ashley Bouder, Megan Fairchild, Tiler Peck, Sterling Hyltin and, in a debut on Thursday, Lauren Lovette.
|
|
If we somehow artificially managed to create an atmosphere (one that also can protect us from UV radiation, in addition to allowing us to breathe, or we'll all get cancer), no magnetic field would still wreak havoc in terms of navigation for both people and animals, we wouldn't have the northern or southern lights (auroras) anymore.
