Submission + - A novel negative entropy source for life on Europa (msn.com)
deglr6328 writes: Richard Greenberg, professor of planetary science at the University of Arizona, has presented findings at the current 41st meeting of the American Astronomical Society ("Vertical Transport through Europa's Crust: Implications for Oxidant Delivery and Habitability") suggesting that the oxygen content of the enormous oceans (suspected to be twice the volume of all Earth's oceans combined) on Jupiter's moon Europa, could be a hundred times higher than the previous estimate — story at MSNBC. Greenberg hypothesizes that the oxygen produced there from radiolysis of Europan surface ice as a result of Jupiter's intensely radioactive magnetosphere, could be sufficient to support ~3 million tons of complex multicellular life, should such life have oxygen requirements comparable to that of terrestrial animals.
