While scientists have not found life on Enceladus, Saturn's moon, they have found the next best thing: food that could sustain potential life. This graphic illustrates how Cassini scientists think water interacts with rock at the bottom of the ocean of Saturn's icy moon Enceladus, producing hydrogen gas. - Hunter Waite , Cassini Ion and Neutral Mass Spectrometer team leadEnceladus is a small, icy moon with a vast ocean beneath its surface. Jupiter's moon Europa has warm, saltwater oceans that could sustain life. Waite said another question could be raised if we discover that Enceladus doesn't support life with so many elements present.
