The Difference Between Ganymede And Callisto Boulder CO (SPX) Jan 26, 2010 
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 mi ... read moreGalileo's Jupiter Journey Began Two Decades Ago 
Pasadena CA (SPX) Oct 19, 2009NASA's Galileo spacecraft began what would become a 14-year odyssey of exploration 20 years ago this Sunday, Oct. 18. Galileo was humanity's first emissary to orbit a planet in the outer solar system - Jupiter. Galileo was launched into space aboard the space shuttle Atlantis on Oct. 18, 1989, from Kennedy Space Center, Florida. The crew of Atlantis deployed Galileo out of the shuttle's ... more

Europa's Ocean Contains Enough Oxygen To Support Life
Tucson AZ (SPX) Oct 09, 2009The global ocean on Jupiter's moon Europa contains about twice the liquid water of all the Earth's oceans combined. New research suggests that there may be plenty of oxygen available in that ocean to support life, a hundred times more oxygen than previously estimated. The chances for life there have been uncertain, because Europa's ocean lies beneath several miles of ice, which separates ... more Ganymede's Magnetosphere Makes Big Impression On Jupiter's Aurora 
Potsdam, Germany (SPX) Sep 21, 2009Studies of features in Jupiter's spectacular and rapidly changing aurorae have given new insights into the complex electromagnetic interactions between the giant planet and two of its innermost moons. 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 ... more First Global Geological Map Of Jupiter Moon Ganymede Completed 
Potsdam, Germany (SPX) Sep 17, 2009Scientists have assembled the first global geological map of the solar system's largest moon - and in doing so have gathered new evidence into the formation of the large, icy satellite. Wes Patterson, a planetary scientist at the Johns Hopkins University Applied Physics Laboratory in Laurel, Maryland, led a seven-year effort to craft a detailed map of geological features on Ganymede, the ... more Asteroid Craters Could Hold Key To Jupiter's Age 
Pasadena CA (SPX) Sep 15, 2009Crater patterns on Vesta and Ceres could help pinpoint when Jupiter began to form during the evolution of the early Solar System. A study modeling the cratering history of the largest two objects in the asteroid belt, which are believed to be among the oldest in the Solar System, indicates that the type and distribution of craters would show marked changes at different stages of Jupiter's ... more |

New NASA Images Indicate Object Hits Jupiter
Pasadena CA (SPX) Jul 21, 2009Scientists have found evidence that another object has bombarded Jupiter, exactly 15 years after the first impacts by the comet Shoemaker-Levy 9. Following up on a tip by an amateur astronomer that a new dark "scar" had suddenly appeared on Jupiter, this morning between 3 and 9 a.m. PDT (6 a.m. and noon EDT) scientists at NASA's Jet Propulsion Laboratory in Pasadena, Calif., using NASA's ... more Probing Antarctica's Lake Bonney 
Moffett Field CA (SPX) May 25, 2009Jupiter's giant moon Europa is one of the few places in our solar system where scientists believe there is a reasonable chance that life has made a home. An ice-covered world with a vast frigid ocean beneath, Europa will not be an easy place to explore. If there is life there, it's likely to be in the ocean, and although the moon's surface may hold clues to what lies below, making a compre ... more Surviving Jovian Doses Of Radiation 
Moffett Field CA (SPX) Jan 20, 2009It's dangerous to remain too long inside the radiation belts of Jupiter. The high-energy particles can damage space probes, and they also can destroy biological molecules or other signatures of life that might exist on inner moons like Europa. A new study plans to determine just how hazardous an impact the radiation belts have on the Jovian system. "Our goal is to find some areas that ... more Underwater Clues To Alien Life 
Amherst MA (SPX) Jan 20, 2009Hovering in a tiny submarine 1.4 miles beneath the Pacific Ocean, a University of Massachusetts Amherst microbiologist felt as if he were in a time machine, witnessing the ancient past, or a scientist’s fantasy future. Just inches away, an undersea volcanic vent called a "black smoker" spewed superheated water, hot gases and heavy-metal precipitates out of the Earth’s crust. James Holden, ... more |
