Description: Voyager 2 obtained this high-resolution picture of Saturn's rings Aug. 22, 1981, when the spacecraft was 4 million kilometers (2.5 million miles) away. Evident here are the numerous "spoke" features, in the B-ring; their very sharp, narrow appearance suggests short formation times. Scientists think electromagnetic forces are responsible in some way for these features, but no detailed theory has been worked out. Pictures such as this and analyses of Voyager 2's spoke movies may reveal more clues about the origins of these complex structures.
