Gravity maps of Enceladus reveal liquid water ocean beneath satellite’s south pole

Scuba divers take note: an underground ocean awaits on a moon of Saturn. Astronomers have, for the first time, measured the depth and extent of a subsurface sea on the ice-covered moon Enceladus. The findings shore up the notion that an underground reservoir feeds the moon’s ice geysers and raise questions about Enceladus’ habitability.
