This is one of those sublime photos from Cassini that just make me smile. Taken on March 24, this raw image shows Rhea, Saturn’s second-largest moon, suspended in orbit in front of the twilight side of Saturn, its rings reduced to a thin ribbon of bands at this viewing angle. The width of the rings is hinted at by their shadows falling onto the southern half of the planet…and little Epimetheus passes by in the background between them and Rhea. Simply beautiful!
Cassini was over 772,000 miles from Rhea when it took this picture.
