Ice Fountains!

I have a bit of a thing for Saturn. It's the show-off of the Solar System with it's beautiful rings and fascinating moons. Browsing on Neatorama, i came across a new picture of the Rings taken by the Cassini orbiter from the dark side of the planet. It shows the rings really vividly, especially the outermost E-ring which is created by the Ice Fountains of the moon Enceladus...



Ice Fountains?! Apparently Enceladus (named after one of the giants who sprang from the union of the blood of Uranus and the Earth) has warm polar regions where ice and ice-water are heated and ejected into space in massive eruptions. The water then freezes back to ice and forms a ring held in orbit around Saturn.
