Pan and Daphnis and their ring waves
Filed under pretty pictures, many worlds, amateur image processing, Saturn's moons, Saturn's rings, Saturn's small moons, Cassini
Patterns at the outer edge of the A ring are excited by the gravitational influence of Pan, upper left, and Daphnis, near the bottom. In this image the rings have been brightened relative to the moons. Pan's saucer shape -- common for Saturn's ringmoons -- is obvious. Pan's longest axis always points toward Saturn.
