In sunlight and shadow

Ooooooo. Saturn casts a long shadow across the rings in this picture, in which Cassini looks across the whole ring plane to where the sunlight peeks out at the far side of the planet. Three moons are visible: most obvious is Tethys, bright and below the rings; above Tethys and a little to the right, just below the F ring, is Pandora; and apparently right next to the planet, though in reality way out on the far side, is Epimetheus.
