NASA recently released a curious new photo of Tethys, one of Saturn’s moons that looks suspiciously like the Death Star, that planet-destroying weapon from the Star Wars series. Tethys is a 660-mile-wide moon that’s made mostly of water ice. It’s that icy surface that gives it such a man-made look.
Plus, the giant crater called Odysseus on its surface. The crater is actually one of the largest craters in the entire solar system!
