Moon Shadow

Saturn is approaching equinox, when the sun will stand directly above its equator and ring system. This means that the moons and moonlets embedded in the rings are presently casting long shadows, and the Cassini probe has been capturing beautiful images of them - as above, where the tiny moon Pan, orbiting in the Enke Gap, casts a slender shadow across the A Ring. There's video too.
