Enceladus Surprise

NASA announced today that Saturn's moon, Enceladus, has geysers of liquid water spouting into space. This is very strange. It is SO cold on that little moon that such a hypothesis seems far-fetched. To make something like that work, you'd need a source of substantial heat, plus well-insulated channels through the icy crust, to the surface. But maybe it happens!

The solar system is a strange, strange place.....
