Have We Discovered Evidence For Life On TitanMoffett Field CA (SPX) Jun 08, 2010 Recent results from the Cassini mission suggest that hydrogen and acetylene are depleted at the surface of Titan. Both results are still preliminary and the hydrogen loss in particular is the result of a computer calculation, and not a direct measurement. However the findings are interesting for astrobiology. Heather Smith and I, in a paper published 5 years ago (McKay and Smith, 2005) suggested that methane-based (rather than water-based) life - ie, organisms called methanogens - on Titan could c ... read more |

WHOI Study Calculates Volume And Depth Of OceansWoods Hole MA (SPX) May 24, 2010 How high is the sky? Scientists have a pretty good handle on that one, what with their knowledge of the troposphere, stratosphere an the other "o-spheres."
