Wallpaper: Tethys Portrait
One of the mid-sized moons of Saturn, Tethys, is thought to be composed almost entirely of water ice. Its most remarkable features are Odysseus, a 400 km wide crater and the Ithaca Chasma a 2,000 km long valley that runs across 2/3 of Tethy‘s globe. Those features are not visible in this image, but what is visible is the slight color variation which almost appears as a “dusting” of color on a largely grey body. A curious feature especially considering the radical color variation found at Iapetus. Perhaps this discoloring is a more subtle result of the same event which caused the strange color variation on Iapetus?
