Close look at the "B-Ring"

Original caption:"This detailed view of Saturn's mid-B ring shows intriguing structure, the cause of which has yet to be explained by ring scientists. The image shows a radial location located between approx. 107.200 to 115.700 Km (about 66.600 to 71.900 miles) from Saturn.
The image was taken with the Cassini spacecraft narrow-angle camera on Sept. 3, 2005, at a distance of approx. 1,1 MKM (roughly 700.000 miles) from Saturn using a filter sensitive to wavelengths of infrared light centered at 752 nnmts. The image scale is 6 Km (about 4 miles) per pixel".
