Saturn's Atmospheric Changes
March 21, 2003
Saturn's rings are bright and its northern hemisphere defined by bright features as NASA's Voyager 2 approaches Saturn, which it will encounter on Aug. 25, 1981. Three images, taken through ultraviolet, violet and green filters on July 12, 1981, were combined to make this photograph. Several changes are apparent in Saturn's atmosphere since Voyager 1's November 1980 encounter, and the planet's rings have brightened considerably due to the higher sun angle. Voyager 2 was 43 million kilometers (27 million miles) from Saturn when it took this photograph.
