Exploring Saturn's Rings

Explanation: By watching a star flicker and fade as it passed behind Saturn's rings, NASA's Voyager 2 spacecraft was able explore the ring system in amazing detail. Data produced by Voyager's instruments as the star Delta Scorpii was occulted by some of the outer rings was used to reconstruct this image which shows details almost 1000 times smaller than normally possible with Voyager's cameras.
