Caption:

Voyager 2 took this picture of Saturn’s faint inner D ring Aug. 25 about 1 hour 48 minutes before the spacecraft’s closest approach to Saturn. The range was 195,400 kilometers (121,300 miles) and phase angle was 166 degrees. This view includes the sun’s shadow across the ring. Voyager 1 saw this region in a similar view last fall, but this higher-resolution image shows many more ringlets and gaps. The D ring is very tenuous and has an extremely small optical depth. The Voyager project is managed for NASA by the Jet Propulsion Laboratory, Pasadena, Calif.
