Moving moons

Cassini strikes again! New images have been released, as well as incredible animated images of moons moving, passing in front of one another, going past Saturn. One, maybe my favorite, is of tiny Pan nestled in the rings of Saturn.

The image above is of Titan (the big fuzzy tennis ball) and Enceladus. At the time Cassini took this shot, Enceladus was 4.1 million kilometers away, and Titan was 5.3 million. Our own Moon is only 384,000 kilometers from Earth, by comparison.’
