Moonshadow on Saturn's rings



The spiky black shadow of Saturn's moon Mimas dips onto the planet's rings and straddles the Cassini Division in this natural color image, taken by the Cassini orbiter as Saturn approaches its August equinox. Shadows on Saturn's rings are extremely elongated at this time in Saturn's 29.5-year orbit because the rings are facing the sun nearly edge-on. The picture was taken on April 8 and released on June 22.
