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

The images were taken by the Wide Field and Planetary Camera 2, developed and built by NASA's Jet Propulsion Laboratory in Pasadena, Calif.

Their results show that Saturn's secondary aurora is much more like Jupiter's in origin than it is the Earth's.

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.

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.

A preliminary analysis of the data from Rosetta's Alice ultraviolet spectrometer indicates that the data quality is excellent and that good science is expected to follow.

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. Fri, 23 Feb 2007 05:00:00 EST http://www.sciencedaily.com/releases/2007/02/070210172729.htm http://www.sciencedaily.com/releases/2007/02/070220150353.htm As NASA develops its next "flagship" mission to the outer solar system, Jupiter's enigmatic moon Europa should be the target, says Arizona State University professor Ronald Greeley. 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.

M. Keck Observatory in Hawaii last month snapped high-resolution near-infrared images of the Great Red Spot, a persistent, high-pressure storm on Jupiter, as an upstart storm, Red Spot Jr., breezed by it on its race around the planet.

For the first time in history, astronomers have witnessed the birth of a new red spot on the giant planet, which is located half a billion miles away. The storm is roughly one-half the diameter of its bigger and legendary cousin, the Great Red Spot.

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.

In research reported in the most recent edition of Geophysical Research Letters, they discovered that Jupiter's x-ray glow is due to x-rays from the Sun being reflected back off the planet's atmosphere.

Katharina Lodders, Ph.D., Washington University in St. Louis research associate professor in Earth and Planetary Sciences in Arts & Sciences, studying data from the Galileo probe of Jupiter, proposes a new mechanism by which the planet formed 4.5 billion years ago.
