As Ganymede and Io orbit Jupiter, they interact with regions of plasma and generate electromagnetic waves that are projected along Jupiter’s magnetic field lines towards Jupiter’s poles where they cause auroral bright spots. Scientists from the University of Liège in Belgium have used thousands of images taken by the Hubble Space Telescope in ultraviolet wavelengths to monitor these auroral features in unprecedented detail.

There are only a handful of known comets where this phenomenon of temporary satellite capture has occurred and the capture duration in the case of Kushida-Muramatsu, which orbited Jupiter between 1949 and 1961, is the third longest.

The spot, caused by the impact of a comet or an asteroid, is changing from day to day in the planet's cloud tops.

Sun, 11 Jan 2009 20:00:00 EST http://www.sciencedaily.com/releases/2009/01/090108082902.htm http://www.sciencedaily.com/releases/2009/01/090105131214.htm The planet Jupiter gained weight in a hurry during its infancy. It had to, since the material from which it formed probably disappeared in just a few million years, according to a new study of planet formation around young stars.

In this crisp Hubble image, Ganymede is shown just before it ducks behind the giant planet.

If the moon Europa is tilted on its axis even slightly as it orbits the giant planet Jupiter, then Jupiter's gravitational pull could be creating powerful waves in Europa's ocean, according to an oceanographer.

Astronomers have found that such moons can be revealed by looking at wobbles in the velocity of the planets they orbit.

This is twice what previous models predicted. Militzer employed a simulation technique designed to model the properties of semiconductors and now used for nanomaterials. This simulation also predicts few ices throughout the rest of the atmosphere.

Called Juno, the mission will be the first in which a spacecraft is placed in a highly elliptical polar orbit around the giant planet to understand its formation, evolution and structure. Underneath its dense cloud cover, Jupiter safeguards secrets to the fundamental processes and conditions that governed our early solar system.

The planet has a mass that is nearly six times that of Jupiter, the largest planet in our solar system. The research sheds light on the ways in which aging stars can influence nearby planets.

This odd aurora revealed itself to one of the infrared instruments on NASA's Cassini spacecraft.

The new image reveals changes in Jupiter's smog-like haze, probably in response to a planet-wide upheaval more than a year ago.

Yet "Europa has the potential for something very similar to hydrothermal systems we have here in our oceans," according to one of the researchers.

Their results show that Saturn's secondary aurora is much more like Jupiter's in origin than it is the Earth's. Sat, 21 Jun 2008 20:00:00 EDT http://www.sciencedaily.com/releases/2008/06/080619105513.htm http://www.sciencedaily.com/releases/2008/05/080522121036.htm The first images of Jupiter since it came out from behind the sun show that the turbulence and storms that have plagued the planet for the past two years continue. Whether or not this is a sign of global warming, the turbulence does seem to be spawning new spots. As Red Spot Jr. and the Great Red Spot approach a June conjunction, a new third spot may merge with the GRS in August. Fri, 23 May 2008 02:00:00 EDT http://www.sciencedaily.com/releases/2008/05/080522121036.htm http://www.sciencedaily.com/releases/2008/05/080521122129.htm Astronomers have found that one of the solar system's largest and newest storms -- Jupiter's Little Red Spot -- has some of the highest wind speeds ever detected on any planet. This is the first time that high resolution, close--up imaging of the Little Red Spot has been combined with powerful Earth--orbital and ground-based imagery made at ultraviolet through mid--infrared wavelengths.

A faint extension of the outermost ring beyond the orbit of Jupiter's moon Thebe, and other observed deviations from an accepted model of ring formation, result from the interplay of shadow and sunlight on dust particles that make up the rings.

Generally, Jupiter's auroral spots result from waves generated by the giant planet's moon Io. The new discovery upsets previous models of how Jovian auroral spots form, and may have implications for our understanding of distant exoplanets which orbit other stars than the Sun.

The discovery overturns a theory that has held sway for more than a generation and has important implications for protecting Earth-orbiting satellites.

New Horizons passed Jupiter on Feb. 28, riding the planet's gravity to boost its speed and shave three years off its trip to Pluto. It was the eighth spacecraft to visit Jupiter -- but a combination of trajectory, timing and technology allowed it to explore details no probe had seen before, such as lightning near the planet's poles, the life cycle of fresh ammonia clouds, boulder-size clumps speeding through the planet's faint rings, the structure inside volcanic eruptions on its moon Io, and the path of charged particles traversing the previously unexplored length of the planet's long magnetic tail.

Their ongoing odysseys mark an unprecedented and historic accomplishment. Voyager 2 launched on Aug. 20, 1977, and Voyager 1 launched on Sept. 5, 1977. They continue to return information from distances more than three times farther away than Pluto.

Astronomers now note the impact hazard posed to Earth by the Centaurs, the parent population of the Jupiter Family of comets. The presence of a Jupiter-like planet in the solar system does not necessarily lead to a lower impact rate at the Earth.

These new views include the closest peek yet at the Earth-sized "Little Red Spot" storm churning materials through Jupiter's cloud tops; detailed images of small satellites herding dust and boulders through Jupiter's faint rings; and of volcanic eruptions and circular grooves on the planet's largest moons.

This flyby gave scientists a unique opportunity to study Jupiter using the package of instruments available on New Horizons, while coordinating observations from both space- and ground-based telescopes including NASA's Chandra X-ray Observatory.

McKinnon, professor of earth and planetary sciences at Washington University in St. Louis, the community suffers from an embarrassment of riches, because each of the moons of Jupiter differs in the way that they can reveal more about planets and how they behave. But he thinks it is Europa that clearly commands the most attention.

Although Europa lies five times farther from the Sun than Earth, he notes it may offer a home for life. He is presenting the Europa proposal today (February 18) at the annual meeting of the American Association for the Advancement of Science in San Francisco.

The spacecraft will study and swing past Jupiter, increasing speed on its voyage toward Pluto, the Kuiper Belt and beyond. The fastest spacecraft ever launched, New Horizons will make its closest pass to Jupiter on Feb. 28, 2007. Jupiter's gravity will accelerate New Horizons away from the sun by an additional 9,000 miles per hour, pushing it past 52,000 mph and hurling it toward a pass through the Pluto system in July 2015.

Massive east-west winds in Jupiter's equatorial region reach approximately 340 miles per hour -- twice as rapid as winds generated by strong hurricanes on Earth. At higher latitudes, the wind pattern switches to alternating jets that race around the planet.
