The
moon Prometheus tugs at an inner strand of Saturn's F ring, as seen by the
Cassini spacecraft.
The
53-mile (86-km) moon is lit on the right by the sun and on the left by
reflected sunlight from Saturn. Some light scattering in Cassini's camera
optics also helped produce the glow on the moon's right side.
Cassini
captured this image from 40 degrees below the ring plane, about 339,000 miles
(546,000 km) from Saturn. NASA extended the probe's four-year mission by two more
years in April 2008, which will give Cassini more opportunities to explore
the Saturn system.
