Thethys, one of Saturn's 33 moons, was photographed quite clearly by Cassini, just under the planet's south pole.
"This latest image in Saturn’s family album was captured on 18 October at a distance of 3.9 million kilometres from Saturn by the Cassini spacecraft. It clearly shows the Ithaca Chasma, a vast trench about 65 kilometres (40 miles) wide, on the surface of Tethys."
The Cassini spacecraft will soon launch the Huygens probe, which will hopefully pierce through the beautiful planet's dense gas cover, land unharmed, and send back pictures of the surface. And maybe an alien or two??
