Saturn's rings - high resolution

March 21, 2003
Voyager 2 obtained this high-resolution picture of Saturn’s rings Aug. 22, 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.
