The_Rings-PIA08900.jpgThe "beginnings" of the Rings55 visiteCaption NASA:"High above the streamers of cloud in Saturn's atmosphere the Planet's immense Ring System begins with faint, thin rings populated with dust-sized ice particles. Here, features in the D-Ring are visible, beginning at about 67.000 Km (approx. 42.000 miles) from the Planet's center.
Stars trail across the background during this exposure, timed to capture the faint light from these D-Ring features.
This view looks toward the unlit side of the Rings, from about 59° above the Ring-Plane.
The image was taken in visible light with the Cassini spacecraft narrow-angle camera on Feb. 9, 2007 at a distance of approx. 1,7 MKM (1,1 MMs) from Saturn.
Image scale is roughly 10 Km (about 6 miles) per pixel".

The_Rings-PIA08990.jpgStartrails through the D-Ring55 visiteCaption NASA:"Faint features in Saturn's innermost ring, the D-Ring, are brought into view in this strongly contrast-enhanced Cassini image. A few background stars are visible through the sheer ring as squiggly star trails.
The inner region of the C-Ring is seen at upper left. The faint diagonal wedge shape on the left side of the image was caused by stray light in the camera optics. The view looks toward the sunlit side of the Rings from about 18° below the Ring-Plane.
The image was taken in visible light with the Cassini spacecraft narrow-angle camera on June 12, 2007 at a distance of approx. 238.000 Km (about 148.000 miles) from Saturn.
Image scale is roughly 1 Km (0,6 miles) per pixel".MareKromium
