A Cassini spacecraft image shows icy geysers spewing from the south polar region of Saturn's moon Enceladus. The salt particles in the ice jets are the strongest evidence to date of a liquid ocean under the moon's icy crust
If water is the elixir of life, it's no wonder that Earth — which is 70% ocean — simply teems with living things. The other planets and moons in the solar system don't have it so good. They're forbidding places that are hydrological deserts, and thus biological ones too.
The moon is thought to have water locked in permafrost at its poles. Jupiter's moon Europa is probably home to a globe-girdling ocean beneath a thin rind of ice, and its Jovian sisters Callisto and Ganymede appear to be icy and wet too. Now, according to new findings by the Cassini spacecraft, one more name can be added to the list of water worlds: Enceladus, a small moon orbiting Saturn. What's more, Enceladus' water might be unusually hospitable to the emergence of life.
