Ocean may lie behind Saturn's biggest moon

A WATERY ocean may lie below the surface of Saturn's largest moon Titan, scientists believe, writes John von Radowitz.

Gravity measurements reveal deformations in Titan's interior that suggest a layer of liquid "sloshing around".

The ocean is thought to be made of water with a depth of 200km. It appears to cover the entire moon beneath 100km of ice.

The evidence comes from space agency Nasa's probe Cassini, which made six fly-bys of Titan between 2006 and 2011.

Scientists used signals beamed back by Cassini to measure distortions in Titan's gravitational field.

The data showed something strange happening in the moon's interior which indicated the presence of liquid water.

Scientists say there are serious doubts whether anything could survive on icy Titan.
