Vast ocean found beneath ice of Saturn moon

(Continued)

Niagara Gazette — "It's extraordinary what Cassini has been able to do for this small moon," California Institute of Technology's David Stevenson, part of the research team, told reporters this week. But "this is not like mapping the surface of the Earth or mapping the surface of the moon, it's nothing like that. It's much cruder, and it's amazing that we've been able to do as much as we can."

Enceladus is hardly the only moon in the solar system with a subsurface sea.

Titan, the largest of Saturn's dozens of moons, is believed to have a global ocean. Evidence points to oceans inside the giant Jupiter moons of Callisto and Ganymede. And Jupiter's Europa also has a hidden reservoir similar to that of Enceladus, complete with plumes and a rocky bottom.

Cassini, already exceeding its life expectancy, is to make three more fly-bys of Enceladus before the mission ends in 2017.
