BBC NEWS | Science & Environment | Enceladus has 'spreading surface': "A US space agency (Nasa) probe has witnessed a moon of Saturn do something very unusual and Earth-like.

Pictures of the icy satellite Enceladus suggest its surface splits and spreads apart - just like the ocean floor on our planet splits to create new crust.

The information was released at a meeting of the American Geophysical Union in San Francisco.

The data from the Cassini spacecraft is said to strengthen the idea that Enceladus harbours a sub-surface sea.

'Bit by bit, we're accumulating the evidence that there is liquid water on Enceladus,' said Carolyn Porco, team leader of the Cassini imaging group and one of the senior scientists on the mission."
