This composite image shows two views of the outer edge of
Saturn's B ring (left) and the inner part of the Cassini Division
(right) in the rings. The images were taken on opposite sides of
the planet Aug. 25 from a range of 610,000 kilometers (380,000
miles). The dramatic result of this comparison is that the thin
eccentric ringlet in the inner gap of the Cassini Division is
shown not to match from side to side; moreover, the edge of the
B ring differs by about 50 km. (30 mi.) as well. Scientists
believe the distorted shape of the B ring edge is due to the
gravitational influence of the Saturnian satellite Mimas. It is
noted, too, that much of the fine B ring structure also
mismatches from side to side, possibly indicating that they are
wave phenomena. The Voyager project is managed for NASA by the
Jet Propuslion Laboratory, Pasadena, Calif.
