Cassini spacecraft image of a disturbance at the outer edge of Saturn's A ring. The disturbance could be caused by an icy body that is in the process of migrating out of the rings causing gravitational effects on the nearby ring particles. This process could be part of the formation of a new moon. The joint NASA-ESA Cassini-Huygens spacecraft was launched in 1997 and took seven years to reach Saturn and its moons. The Huygens probe separated from Cassini on 25th December 2004, and descended to the surface of Saturn's largest moon, Titan. The Cassini orbiter continued orbiting Saturn; studying its atmosphere and rings and performing flybys of its moons. Image obtained by Cassini's narrow-angle camera on 15th April 2013 at an approximate distance of 1.2 million kilometres from Saturn.
