Saturn's icy moon Enceladus is looking more and more like a habitable world. The same sorts of chemical reactions that sustain life near deep-sea hydrothermal vents here on Earth could potentially be occurring within Enceladus' subsurface ocean, a new study published today (April 13) in the journal Science suggests. These reactions depend on the presence of molecular hydrogen (H2), which, the new study reports, is likely being produced continuously by reactions between hot water and rock deep down in Enceladus' sea. read more http://www.nbcnews.com/mach/space/nasa-discovers-ingredients-life-saturn-s-moon-enceladus-n746166
