Saturn's Cleanest Moon: Enceladus

Enceladus, one of Saturn's moons, is composed mostly of water ice, giving it the purest and cleanest ice surface in the Solar System. Its surface has unusual grooves and few craters, suggesting it is geologically young or recently reformed. Some astronomers speculate that Enceladus might have a form of volcanic activity, perhaps involving water.
