A look at the ringed planet from NASA’s Cassini spacecraft.
A giant of a moon appears before a giant of a planet undergoing seasonal changes in this natural-color view of Titan, left, and Saturn from NASA's Cassini spacecraft. Titan, Saturn's largest moon, measures 3,200 miles across and is larger than the planet Mercury. As the seasons have changed on Saturn, and spring has come to the north and autumn to the south, the azure blue in the northern Saturnian hemisphere that Cassini observed in 2004 is now fading.
