Saturn’s “Flying Saucer” Moons
It’s been known for a while that two of Saturn’s ring moons, Pan and Atlas, were wider than they were tall. But it was only now that the Cassini spacecraft has imaged them that it was revealed that they look like flying saucers.
Scientists think that the smooth ridges around the moons’ middles is an accumulation of material from Saturn’s rings, and that the accumulation has now ceased. RTWT
