Cassini, Encke and Keeler: bright arcs in the shadow of the Rings

Saturn's Rings throw imposing shadows and relegate parts of the Planet's Northern Regions to darkness. Three thin and bright arcs in this scene represent three well-known gaps in the immense Ring System. From bottom to top here (and widest to thinnest) they are the Cassini Division, the Encke Gap and the Keeler Gap.
The image was taken in infrared light (752 nnmts) using the Cassini spacecraft wide-angle camera on Oct. 29, 2005, at a distance of approximately 446.000 Km (about 277.000 miles) from Saturn.
The image scale is 23 Km (roughly 14 miles) per pixel.
The image was contrast enhanced to improve visibility of features in the atmosphere.
