Saturn and its rings, Cassini image. The rings are silhouetted against the partially sunlit planet. This view looks toward the unilluminated side of the rings from about 7 degrees below the ring plane. Saturn is a large gas giant planet, with a ring system that consists of thousands of chunks of rock and ice. This view, from a distance of around one million kilometres, was taken in green light. The image was obtained on 18 January 2017, with the wideangle camera of Cassinis Imaging Science Subsystem (ISS). The Cassini spacecraft has been surveying the Saturnian system since 2004, with its mission scheduled to end in September 2017.NasaJplCaltechSpace Science InstituteScience Photo Library
