— “We think that the temperature at least in some part of the ocean must be higher than 190 degrees Fahrenheit. If you could swim a little bit further from the really hot part, then it could be comfy.”

— “[For such heat] the most exciting possibility is that there's ongoing chemical reactions between the rock inside Enceladus and the water.”
- Bill McKinnon, Ph.D., Planetary Scientist, Washington Univ.-St. LouisMarch 12, 2015 Boulder, Colorado - NASA's Cassini spacecraft has found evidence of ongoing hydrothermal activity on Enceladus, one of Saturn's 31 moons and the sixth largest. In the March 11, 2015 issue of Nature, postdoctoral researcher, Sean Hsu, Ph.D., and colleagues at the Laboratory of Atmospheric and Space Physics at the University of Colorado in Boulder, have found that microscopic grains of silica detected near Saturn are most likely spewed out from the watery geysers on Enceladus. Dr. Hsu says in a March 11, 2015, LASP press release: “It's very exciting that we can use these tiny grains of rock, spewed into space by geysers, to tell us about conditions on — and beneath — the ocean floor of an icy moon.”
