The Hubble Space Telescope captured Saturn and four of its icy moons: Mimas, Enceladus, Dione, and Tethys. The four moons' shadows appear to skirt the planet just above the shadow of Saturn's rings. This week, astronomers announced the discovery of Saturn's 60th moon, orbiting between Mimas and Enceladus.
