The Telegraph teases me with the promise of life on Enceladus:
Nasa’s Cassini spacecraft flew through icy plumes created by ice volcanoes and detected negatively charged water molecules, in a clear sign an underground sea exists.
On Earth this short-lived type of ion is produced where water is moving, such as in waterfalls or crashing ocean waves.
British scientists, reporting in the journal Icarus, say it is known that the jets contained water but it was not clear before whether this might be liquid.
If there is liquid water on Enceladus, Nasa scientists believe Saturn’s sixth-largest moon could have the conditions necessary to sustain life.
Water plus carbon plus stuff moving around = a good chance something could survive up there.
