MOONS OF SATURN : Enceladusby Lauren Effron and Dave Mosher
 Welcome to Enceladus, one of Saturn's icy inner moons. The streams of light you see are actually jets of water shooting out of the surface. The Cassini spacecraft discovered the geysers in December 2005, shown here in false-color. Researchers think gravitational kneading of its core heats subsurface water into vapor, causing it to spew out of the moon's chilly -328 degrees F surface. For a full-resolution image, click here.
