Methone: 3-kilometer diameter Smooth Egg Moon of Saturn - Why is this moon shaped like a smooth egg? The robotic Cassini spacecraft completed the first flyby ever of Saturn's small moon Methone in May and discovered that the moon has no obvious craters. Craters, usually caused by impacts, have been seen on every moon, asteroid, and comet nucleus ever imaged in detail -- until now.

Moons of Saturn : Tethys Discovery News This 665 mile wide moon of Saturn, , pronounced "teeth-this," has an ice-covered surface criss-crossed with cracks and faults. In this Cassini snapshot, a small mountain range inside the Odysseus crater can be seen. Covering about two-fifths of Tethys' surface, the crater is enormous, and the mountains are thought to have formed from shifting surface ice.  CREDIT: NASA/JPL/SPACE SCIENCE INSTITUTE

Moons of Saturn : Janus Discovery News Janus is a tiny, potato-shaped satellite that is typical of Saturn's 17-plus moons: cratered and icy. It's the big brother to the moon Epimetheus, which hangs out in nearly the same orbit. By studying Cassini spacecraft images closely, scientists have noticed both moons hang out in a thin but wide ring of dust and ice -- likely the leftovers of meteorite impacts over the eons.

Moons of Saturn : Phoebe Discovery News This hunk of rock circling Saturn under the guise of a moon could have once been a comet. Cassini snapped this photo on June 30, 2004 and researchers have since been studying its unusual pox surface, backwards orbit, low density and extremely dark features. They think Phoebe might have been a Kuiper Belt object close to Neptune before Saturn's gravitational pull snagged it.  CREDIT: CASSINI IMAGING TEAM/SSI/JPL/ESA/NASA

Moons of Saturn : Titan Discovery News Titan, mightiest of all the Saturn moons, a sort of early Earth chock full of organic compounds and a thick atmosphere. In January 2005, the Huygens probe landed on Titan's surface, revealing many of the orange-brown world's secrets. That makes Titan the only moon aside from Earth's to receive a robotic surface visit from humans. This false-color photo shows Titan's surface in green CREDIT: NASA/JPL/SPACE SCIENCE INSTITUTE

Moons of Saturn : Epimetheus Discovery News  Set against a large smoky Titan and Saturn rings, Epimetheus stands out as the "lil' white moon," as scientists have nicknamed it. This image is in false color, but not without purpose. It allows us to see Titan, Saturn and Epimetheus clearly and compare their sizes -- Epimetheus is 72 miles across while giant Titan is 3,200 miles across.  CREDIT: NASA/JPL/SPACE SCIENCE INSTITUTE

Moons of Saturn : Dione Discovery News Giovanni Cassini, who spent a good part of his life looking at Saturn through a telescope, discovered Dione in 1684. Like most Saturn satellites, it's made mostly of ice. The Cassini spacecraft -- named after you-know-who -- found cliffs of ice hundreds of feet high in late 2004. Scientists think movement of the crust split it open to create the towering structures.  CREDIT: NASA
