 A total of 126 images taken over the course of two hours make up this mosaic picture of Saturn. The Cassini-Huygens spacecraft snapped the photos on October 6, 2004, when it was approximately 3.9 million miles (6.3 million kilometers) from Saturn. Cassini was on a four-year mission to explore the ringed planet.
