Saturn moon may have hidden ocean

Saturn's moon Titan may have a deep, hidden ocean, according to data published in the journal Science.

Radar images from the Cassini-Huygens mission reinforce predictions that a reservoir of liquid water exists beneath the thick crust of ice.

If confirmed, it would mean that Titan has two of the key components for life - water and organic molecules.

Currently, three other Solar System objects are suspected of having deep oceans: Ganymede, Callisto and Europa.
