Christmas a la Cassini

Since it's Saturnalia, or thereabouts, let's take a look at some of the Cassini images I missed over the past few months:

The familiar icon of a crescent moon is rendered alien in this view of Enceladus bisecting a slender crescent of Saturnian daylight.

Another snap from the same flyby shows Enceladus' characteristic geysers.

Cassini caught a good portrait here of one of Saturn's many smaller, potato-shaped moons: Helene.

Saturn's second largest moon, Rhea, eclipses Titan in a grab for the limelight. Rhea is about a million kilometres away in this image, and Titan 2 million.

Saturn has many cratered, icy moons, but Tethys here shows off one of its most remarkable features: Ithaca Chasma, a massive canyon dwarfed only by Valles Marineris on Mars.

Happy Christmas everyone - whatever planet, moon or ring-system you may call home.

Merry Christmas! I wonder why some of the moons are perfectly round while others are not. Hmmm.

Good Yule, Happy (belated) Solstice. Wonderfully stark images.

Happy, merry Merry Christmas, Pacian and Space Cat!

@All: Thanks, you too!

@Michelle: It's a matter of size, more or less. The more massive moons have stronger gravity, which smooths out their bumps and irregularities.
