The Rings' texture

Caption NASA:"This close-up of the inner edge of the Cassini Division shows an enormous amount of structure, including a grainy texture in the bright outer B-Ring material near the gap edge.
An extreme enhancement of the original image, presented at right, reveals the grainy region with greater clarity.
This view looks toward the lit side of the rings from about 54° below the Ring-Plane.

The image was taken in visible light with the Cassini spacecraft narrow-angle camera on Nov. 8, 2006 at a distance of approx. 378.000 Km (about 235.000 miles) from Saturn and at a Sun-Saturn-spacecraft, or phase, angle of 68°.
Image scale is roughly 2 Km (a little more than 1 mile) per pixel".
