This July 29, 2013 image provided by NASA shows that Winter is approaching in the southern hemisphere of Saturn and with this cold season has come the familiar blue hue that was present in the northern winter hemisphere at the start of NASA's Cassini mission. This view looks toward the non-illuminated side of the rings from about 44 degrees below the ring plane. Images taken using red, green and blue spectral filters were combined to create this natural color view. The images were taken with the Cassini spacecraft wide-angle camera. The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency. (AP Photo/NASA/JPL-Caltech/Space Science Institute) ORG XMIT: LA113
