Images: Hot spot on Saturn
A new set of infrared images taken by the Keck I telescope in Hawaii shows a warm polar hot spot at Saturn's south pole.

This picture is a composite of 30 images from ESA's Huygens probe as it was decending toward the surface of Titan. The images were taken from an altitude between 8 kilometers and 13 kilometers.

This is a colorized view of the surface of Titan taken by the European Space Agency's Huygens probe. The two rock-like objects just below the middle of the image are about 6 inches (left) and about 1.5 inches (center) across respectively, at a distance of about about 33 inches from Huygens.

New images hint that the streaks visible on the surface of Dione are not ice, as previously believed, but cliffs.

Scientists captured images of the polar clouds of Titan in October. The appearance recently of other clouds (right), though, has been a surprise.

Prominent in the center of this image of Titan, taken Dec. 10 on Cassini's return trip, is Xanadu, a broad bright area. There is also a bright 345-mile semi-circle to the lower right on Xanadu, as well as a 205 mile multi-ringed feature to the upper right.

Look closely and you'll see a trail of particles from Saturn's F ring to Prometheus, a moon that's 63-miles wide. Or, is the stream from Prometheus to the F ring?
