Vast ocean found beneath ice of Saturn moon

This illustration provided by NASA and based on Cassini spacecraft measurements shows the possible interior of Saturn's moon Enceladus - an icy outer shell and a low-density, rocky core with a regional water ocean sandwiched in between the two at southern latitudes. Plumes of water vapor and ice, first detected in 2005, are depicted in the south polar region.
