Jupiter's moon Io could be a potential target to look for extraterrestrial life. Io is the innermost of Jupiter's large moons and has the most volcanic activity in the solar system, with plumes of matter rising 186 miles above the surface. This activity is due to Jupiter's powerful gravitational pull, which causes Io's tormented solid crust to bulge up and down 328 feet or more, generating intense heat in Io due to friction. Io generally is considered a poor candidate for life because of...

On June 3rd, 2010, something hit Jupiter. A comet or asteroid descended from the black of space, struck the planet's cloudtops, and disintegrated, producing a flash of light so bright it was visible in backyard telescopes on Earth. Soon, observers around the world were training their optics on the impact site, waiting to monitor the cindery cloud of debris which always seems to accompany a strike of this kind. They're still waiting. "It's as if Jupiter just swallowed the thing whole," says...

CANNES, France, June 11 /PRNewswire/ -- The highly anticipated Esimit Europa 2 (www.esimit.com) yacht has been introduced to the global audience at its christening ceremony, which was attended by numerous business leaders and project supporters. The 30-meter long and 44-meter high giant is the fastest yacht in the world. Under the patronage of Jose Manuel Barroso, the President of the European Commission, the yacht is building upon its 15-year tradition of connecting European nations....

Lost: A giant belt of brown clouds big enough to swallow Earth twenty times over. If found, please return to Jupiter. In a development that has transformed the appearance of the solar system's largest planet, one of Jupiter's two main cloud belts has completely disappeared. "This is a big event," says planetary scientist Glenn Orton of NASA's Jet Propulsion Lab. "We're monitoring the situation closely and do not yet fully understand what's going on." Known as the South Equatorial Belt (SEB),...

Extraordinarily rare springs high above the rest of the world in the Arctic could serve as Earth's own little version of Europa, helping scientists picture what life might face on the mysterious Jovian moon. Europa is covered with sulfur-rich materials concentrated along cracks and ridges on its icy surface, which could hold the only clues we currently have about the composition of its hidden underground ocean. These compounds in the ice might even contain organic material that migrated...

When NASA's Galileo probe reached Jupiter in 1995 and began sending back data about the gas giant, astronomers were in for a surprise: Jupiter was unusually poor in helium and neon, the two lightest noble gases. New simulations of the physics inside the planet reveal why. The results, which provide a glimpse into Jupiter's turbulent innards, are reported in the current issue of Physical Review Letters and highlighted with a Viewpoint by Jonathan Fortney (University of California, Santa Cruz)...

New thermal images from powerful ground-based telescopes show swirls of warmer air and cooler regions never seen before within Jupiter's Great Red Spot, enabling scientists to make the first detailed interior weather map of the giant storm system. The observations reveal that the reddest color of the Great Red Spot corresponds to a warm core within the otherwise cold storm system, and images show dark lanes at the edge of the storm where gases are descending into the deeper regions of the...

Differences in the number and speed of cometary impacts onto Jupiter's large moons Ganymede and Callisto some 3.8 billion years ago can explain their vastly different surfaces and interior states, according to research by scientists at the Southwest Research Institute appearing online in Nature Geoscience Jan. 24, 2010. Ganymede and Callisto are similar in size and are made of a similar mixture of ice and rock, but data from the Galileo and Voyager spacecraft show that they look different at...

Planetary scientist Francis Nimmo will outline the impact of ice dynamics on the habitability of the moons of Saturn and Jupiter on Tuesday, December 15, at the annual meeting of the American Geophysical Union in San Francisco. Scientists once thought that life could originate only within a solar system's "habitable zone," where a planet would be neither too hot nor too cold for liquid water to exist on its surface. But according to Nimmo, a professor of Earth and planetary sciences at the...

Amateur astronomers, enthusiasts and the general public will be taking part in a three-day sky watching party this week in order to celebrate the achievements of Galileo. Dubbed the "Galilean Nights," the party will last from October 22 to 24. The purpose of the celebration is to allow people in countries across the globe to gaze into the sky, many of them for their first time. The event is being promoted by the International Astronomical Union (IAU). It is said to include more than 1,000...

Satellite -- A satellite is an object that orbits another object. With sufficient tangential velocity, the object does not collide with the primary object it orbits, but maintains a distance from that object as the rate at which it falls towards that object is similar to the rate that it travels away, thus the object orbits the primary object and becomes a satellite. In other words: gravitational force serves as the centripetal force needed to make the object circle the primary...

Galileo Probe -- The Galileo probe was an unmanned probe sent by NASA to study the planet Jupiter and its moons. Named after the astronomer Galileo Galilei, it was launched on October 18 1989 by the Space Shuttle Atlantis and arrived at Jupiter on December 7 1995. Galileo's launch had been significantly delayed by the hiatus in Space Shuttle launches that occurred after the Space Shuttle Challenger disaster, and new safety protocols that were implemented as a result forced Galileo to use...

Retrograde Motion -- Retrograde motion is the orbital motion of a body in a direction opposite that which is normal to spatial bodies within a given system. 'Retrograde' derives from the Latin words retro, backwards, and gradus, step. In the Solar system, mostly everything rotates in the same sense: all major planets orbit the Sun counterclockwise as seen from the pole star (Polaris). Most planets spin in the same sense, including Earth. The same happens with the orbital motions of the...

Planetary Ring -- A planetary ring is a ring of dust and other small particles orbiting around a planet in a flat disc-shaped region. The most spectacular and famous planetary rings are those around Saturn, but all four of the solar system's gas giant planets (Jupiter, Saturn, Uranus, Neptune) possess ring systems of their own. The origin of planetary rings is not precisely known, but they are thought to be unstable and dissipate over the course of tens or hundreds of millions of...

Jupiter's Moon Himalia -- Himalia is Jupiter's tenth moon. Himalia is 110 miles (170 km) in diameter and orbits 7,000,000 miles (11,480,000 km) from Jupiter. Himalia has a mass of 9.5 x 1018kg. It orbits Jupiter in 250.5662 (Earth) days. Very little is known about Himalia. Himalia was discovered by C. Perrine in 1904. Orbital eccentricity is 0.15798. Orbital inclination is 27.63 degrees. Orbital period is 250.5662 days. Rotational period is 0.4 day. ----- NASA...
