Underwater Clues To Alien Life Amherst MA (SPX) Jan 20, 2009 
Hovering 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 ... read moreSurviving 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

Hubble Catches Jupiter's Largest Moon Going To The Dark Side
Tempe AZ (SPX) Dec 19, 2008NASA's Hubble Space Telescope has caught Jupiter's moon Ganymede playing a game of "peek-a-boo." In this crisp Hubble image, Ganymede is shown just before it ducks behind the giant planet. Ganymede completes an orbit around Jupiter every seven days. Because Ganymede's orbit is tilted nearly edge-on to Earth, it routinely can be seen passing in front of and ... more Unmasking Europa 
Moffett Field CA (SPX) Dec 16, 2008What lies beneath Europa's icy crust? Richard Greenberg has been pondering this question for 30-odd years. His new book, Unmasking Europa, describes his view that Europa's hidden ocean and the life forms it may support are not that far below the surface. A professor in the Lunar and Planetary Laboratory at the University of Arizona, Greenberg was one of the first to formulate how tidal for ... more Europa Does The Wave To Generate Heat 
Seattle WA (SPX) Dec 15, 2008One of the moons in our solar system that scientists think has the potential to harbor life may have a far more dynamic ocean than previously thought. 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 Robert Tyler, an oceanographer with the ... more Exploring Europa On Earth 
Moffett Field CA (SPX) Dec 09, 2008Beneath the ice-covered surface of Jupiter's giant moon Europa, a vast ocean circles the globe. It is one of the few places in our solar system where, scientists believe, life may have taken hold. Various ideas have been proposed about how life could survive in that frigid environment. One suggestion is that hydrothermal vents, like those that dot the floor of Earth's oceans, are also pres ... more

NASA Prepares For New Juno Mission To Jupiter
Washington DC (SPX) Nov 25, 2008NASA is officially moving forward on a mission to conduct an unprecedented, in-depth study of Jupiter. 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 ... more Titan Is Electric 
Moffett Field CA (SPX) Oct 29, 2008Many scientists believe that precursor molecules for life are more likely to form on planets or satellites where electrical storms occur in the atmosphere. Physicists at the University of Granada and the University of Valencia (Spain) have been analyzing data sent by the Huygens probe from Titan, the largest moon of Saturn, and have proved "in an unequivocal way" that there is natural elec ... more Jet Streams On Giant Planets 
Tuscon AZ (SPX) Oct 14, 2008Turbulence generated by thunderstorms can drive the multiple east-west jet streams on the giant planets -- Jupiter, Saturn, Uranus, and Neptune -- and explain a long-standing conundrum concerning the puzzling differences between the innermost two planets, Jupiter and Saturn, and the outermost two, Uranus and Neptune. Scientists have been trying to understand the mechanisms that form the ... more Studying A Giant Planet
Moffett Field CA (SPX) Oct 10, 2008For generations, astronomers have argued over how the planets in our solar system were formed. Today, most theories assume that planets were formed in a nebula of gas and dust that condensed around what eventually became our sun, but there is still great disagreement over details, particularly for gas giant planets like Jupiter: Did a small core form first around which each planet condensed, or ... more
