Move Over Caravaggio: Cassini's Light and Dark Moons:

NASA's Cassini spacecraft has returned Saturnian moon images from its flyby late last week, revealing light and dark contrasts worthy of chiaroscuro painters like Caravaggio. The flyby on August 13 targeted the geyser moon Enceladus, but also brought Cassini close to two other moons--Tethys and Dione.
