Enceladus-Cassini_big.jpgIs there "Life" underneath Enceladus?!?56 visiteCaption NASA:"Could life exist beneath Enceladus?
A recent flyby of Saturn's icy moon has bolstered this fascinating idea. Two years ago, images from the Cassini Spacecraft led astronomers to the undeniable conclusion that Saturn's moon Enceladus was spewing fountains of gas and ice crystals through cracks in its surface (the "Tiger Stripes").
Last month (February 2008), Cassini dove through some of these plumes and determined that they contained Water Vapor laced with small amounts of Methane as well as simple and complex organic molecules. Surprisingly, the plumes of Enceladus appear similar in make-up to many comets.
What's more, the temperature and density of the plumes indicate they might have originated from a warmer source - possibly a liquid source - beneath the surface.
A liquid water sea containing organic molecules is a good place to look for life.
Pictured above is a vertically exaggerated close-up of some long, venting Tiger Stripes. The computer composite was generated from images and shadows taken during the recent Cassini flyby.
Nine more flybys of Enceladus by Cassini are planned".MareKromium

Janus-PIA09871.jpgJanus and Saturn (natural colors; credits: Lunexit)56 visiteCaption NASA:"The Cassini Spacecraft provides a window on the awesome scale of the Saturn System, with the Giant Planet dominating one of its smaller satellites.
Orbiting here, just outside the Main Ring System, is Janus.
This view looks toward the unilluminated side of the Rings from about 16° above the Ring-Plane. The image was taken in visible light with the Cassini spacecraft narrow-angle camera on Feb. 13, 2008. The view was obtained at a distance of approx. 1,6 MKM (about 1 MMs) from Janus and approx. 1,8 MKM (about 1,1 MMs) from Saturn.
Image scale is roughly 10 Km (about 6 miles) per pixel on Janus".MareKromium
