Deep inside the "C-Ring"

Original caption:"This close-up view shows an inner region of Saturn's C-Ring. It covers a radial location on the rings located approx. 78.000 to 80.500 Km (about 48.500 to 50.000 miles) from the center of the Planet. Saturn itself has a radius of 60.330 Km (that is about 34.490 miles).
A bright feature, informally referred to as a "plateau", arcs across the image center. The plateau is not high in terms of elevation, but rather in terms of particle density (seen here as brightness). The density is fairly uniform within the bright band, and some five times higher than in the surrounding ring structure. Although the many plateaus in Saturn's Rings appear unchanged over 25 years of observations, scientists do not know what determines their locations or maintains their sharp boundaries.
The image was taken in visible light with the Cassini spacecraft narrow-angle camera on Sept. 5, 2005, at a distance of approx. 418.000 Km(such as about 260.000 miles) from Saturn. The image scale is 2 Km per pixel".
