Cassini spacecraft investigates the Saturnian moon Enceladus

BBC : Photos taken by the Cassini spacecraft during an 11 August flyby of Saturn’s moon Enceladus have been released to the public. The pictures show previously unseen detail in the so-called tiger stripes that mark the south pole of Enceladus. These cracks run across a “hot-spot” region that is hurling plumes of ice particles into space.Project scientists are intrigued by what might be driving this activity; and some have suggested the mechanisms involved could be sufficient to maintain a mass of liquid water below the moon’s surface.
