Scientists in the UK have been analyzing the results from NASA's Cassini-Huygens mission to Saturn and its moons and they've made some fascinating discoveries.  They have detected some necessary ingredients for life on Enceladus, one of Saturn's many moons.  The probe flew through a water ice plume and detected negative ions, leading scientists to believe that significant, active sub-surface water exists on Enceladus and an environment could exist there with the ability to support life.
