Saturn's A Ring Has Oxygen, But Not Life

[LARRY KLAES]

http://www.spacedaily.com/news/cassini-05zc.html   Data from the Cassini-Huygens satellite showing oxygen ions in the atmosphere around Saturn's rings suggests once again that molecular oxygen alone isn't a reliable indicator of whether a planet can support life. That and other data are outlined in two papers in the Feb. 25 issue of the journal Science co-authored by University of Michigan engineering professors Tamas Gombosi, J. Hunter Waite and Kenneth Hansen; and T.E. Cravens from the University of Kansas.
