2. Saturn's Enceladus moon hides 'great lake' of water

Jets of water-ice are blasted thousands of km above the surface of Saturn's tiny moon Enceladus

The evidence for an "ocean" of water under the surface of Saturn's moon Enceladus appears to be overwhelming.

The little world has excited scientists ever since jets of icy material were seen squirting into space from a striped region at its south pole.

Now, exquisite measurements using Nasa's Cassini probe as it flew over the moon have allowed researchers to detect the water's gravitational signal.

Science magazine reports the details.

"The measurements that we have done are consistent with the existence of a large water reservoir about the size (volume) of Lake Superior in North America," Prof Luciano Iess told BBC News.
