As you look at this photo, try to remember that every single pixel represents about a quarter-mile. This is just one short section of the outer B ring, which is perturbed by the nearby moon Mimas. Every time Mimas orbits Saturn, particles in this ring orbit twice, creating a periodic tugging motion that shifts the particles. The image has been cleaned up to remove blemishes so that you can appreciate the ring structure without underlying distractions.
