This image of the northern hemisphere of Saturn was taken by NASA's Voyager 1 on Nov. 5, 1980 at a range of 9 million kilometers (5.5 million miles) shows a variety of features in Saturn's clouds: Small-scale convective cloud features are visible in the dark belt (center); an isolated convective cloud with a dark ring is seen in the lighter zone; and a longitudinal wave is visible in the brighter zone (right of center belt). The smallest features visible in this photograph are 175 kilometers (108.7 miles) across. The Voyager project is managed for NASA by the Jet Propulsion Laboratory, Pasadena, Calif.
