Saturn and some of His Moons

How thin are the Rings of Saturn? Brightness measurements from different angles have shown Saturn's rings to be about 1 Km thick, making them many times thinner, in relative proportion, than a razor blade. This thinness sometimes appears in dramatic fashion during an image taken nearly along the Ring-Plane. The Cassini spacecraft now orbiting Saturn has captured another shot that dramatically highlights the Ring's thinness. The above artistic looking image was taken early last month in infrared polarized light. If alone in space, the unlit part of Saturn would be much darker. Reflection of light off of moons (...) and the billions of small particles in Saturn's Rings, however, gives the giant space orb an unusual glow, an effect highlighted in polarized light.

W00012439.jpg was taken on December 17, 2005 and received on Earth December 18, 2005. The camera was pointing toward PROMETHEUS from a distance of approximately 2.830.065 Km.
The image was taken using the CL1 and CL2 filters.
