Enceladus, one of Saturn's moons of only
about 314 miles in diameter hides in its entrails an ocean of liquid water that
is rich in organic molecules, making it one of the places where it is most
likely to find some form of extraterrestrial life.
Europa is a strange
shaped moon of Jupiter with a large number of intersecting lines. Models
from the interior of Europe show that under a thin crust of 5 km (3 miles) of
water ice, Europa can have oceans with 50 km (30 miles) of depth or more. The
visible marks of Europa could be the result of a global expansion where the
crust could have been fractured, filled with water and frozen.
