Titan, moon of Saturn. Rivers of running methane... awesome.

The clouds that make Titan featureless in visible light have now been pierced several times in infrared light by the robot Cassini spacecraft currently orbiting Saturn. These images have been compiled into the above time-lapse movie.

Saturn’s sponge-like moon Hyperion. Hyperion is shaped a bit like a potato and, with dimensions of 410 x 260 x 220 km, is one of the largest bodies in the Solar System known to be so irregular. Its odd, almost ‘bubbly’ appearance, can be attributed to it having a very low density for its size. Because of these properties the entire moon is porous, like a sponge, with well-preserved craters of all shapes and sizes packed together across its surface. Scientists think that this moon is mostly…

This stunning false-color view of Saturn's moon Hyperion reveals crisp details across the strange, tumbling moon's surface. Differences in color could represent differences in the composition of surface materials.

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.

An egg in space. Cassini photographed and egg shaped moon in It was named Methone.

In the foreground there are six round fully illuminated bodies and some small irregular objects. A large half-illuminated body is shown in the background with circular cloud bands around the partially darkened north pole visible.

Images of several moons of Saturn. From left to right: Mimas, Enceladus, Tethys, Dione, Rhea; Titan in the background; Iapetus (top) and irregularly shaped Hyperion (bottom). Some small moons are also shown. All to scale.

The scene features Titan, largest, and Dione, third largest moon of Saturn.  Pale Dione is about 1,100 kilometers across and orbits over 300,000 kilometers from the visible outer edge of the A ring. At 5,150 kilometers across, Titan is about 2.3 million kilometers from Cassini, while Dione is 3.2 million kilometers away.

Orbiting in the plane of Saturn's rings, Saturnian moons have a perpetual ringside view of the gorgeous gas giant planet. - Which doesn't matter because only Cassini can see it.

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 : 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.

NASA's Cassini orbiter captured this view of Saturn on June 15, from a distance of about 1.8 million miles (2.9 million kilometers). The rings' shadow runs across the planet's sunlit side. The speck in the lower left corner is Enceladus, a 313-mile-wide (504-kilometer-wide) moon of Saturn.

Angling Saturn Cassini takes an angled view toward Saturn, showing the southern reaches of the planet with the rings on a dramatic diagonal. The rings cast wide shadows on the planet’s southern.
