Pan (28 kilometers, 17 miles across) occupies the Encke gap at the center of this image, which also displays some of the A ring’s intricate wave structure. The two most prominent bright banded features seen on the left side of the image are spiral density waves, which propagate outward through Saturn’s rings. The bright crests represent areas with higher ring particle densities. The image was taken in visible green light with the narrow angle camera on Aug. 1, 2005, from a distance of approximately 794,000 kilometers (493,000 miles) from Pan. The image scale is 5 kilometers (3 miles) per pixel.
