A Hot Start Might Explain Geysers on Enceladus

A hot start billions of years ago might have set into motion the forces that power geysers on Saturn's moon Enceladus. &quot;Deep inside Enceladus, our model indicates we've got an organic brew, a heat source and liquid water, all key ingredients for life,&quot; said Dr.

An embryonic star, just beginning its life as the center of a planetary system, is apparently deluged with massive rainfall as icy material vaporizes and refreezes. Astronomers are observing one such star in a nebula about 1,000 light years from Earth with the Spitzer Space Telescope.

Scientists taking their first "sniffs of air" from planets outside our solar system are a bit baffled by what they didn't find: water.

Recent analyses of ESAÃ¢ÂÂs Mars Express data reveal that concentrations of water vapour and methane in the atmosphere of Mars significantly overlap. This result provides important new hints to evaluate the hypothesis of present life on the Red Planet.

Astronomers from the University of Virginia and other institutions have found that Enceladus, the sixth-largest moon of Saturn, is a &quot;cosmic graffiti artist,&quot; pelting the surfaces of at least 11 other moons of Saturn with ice particles sprayed from its spewing surface geysers.

LONDON - A large, icy rock at the edge of our solar system was warm at some point, a finding that suggests planetary processes like volcanic activity, astronomers say.

Mars shows signs of geologically recent volcanic activity, and scientists find to their surprise that there might well be another volcanic blast in the Red Planet&#39;s future.
