This computer-enhanced photo of Saturn, taken
Nov. 13, 1980, by Voyager 1, shows Saturn's rings and their shadows
against the lighted crescent of the planet. The photo was taken
from a distance of 1,570,000 kilometers (930,000 miles) beyond
the planet. The bright, overexposed limb of Saturn is visible
through the rings. The inner or C-ring scatters light in a way
that causes it to look bluer that the outer A- and B- rings. Radial
spokes in the B-ring, which appeared dark in pictures taken when
Voyager 1 was approaching Saturn, can be seen here as bright markings.
This information can be used to help determine the nature of individual
particles in the rings. The thin F-ring displays brightness variations
that are caused by non-uniform distribution of material in the
ring. Jet Propulsion Laboratory manages the Voyager project for
NASA's Office of Space Science. (P-23346)
