Shadows (Natural Colors; credits: NASA/JPL/Space Science Institute)

Caption NASA:"Saturn's Rings cast a dramatic shadow separating the blues and greens of the Planet's Northern Hemisphere from the creamy pastels coloring the Southern Hemisphere.

This mosaic combines 6 images — 2 each of red, green and blue spectral filters — to create this Natural Color view. The images were obtained with the Cassini Spacecraft wide-angle camera on Dec. 30, 2008 at a distance of approx. 1,2 MKM (such as about 750.000 miles) from Saturn and at a Sun-Saturn-Spacecraft, or Phase, Angle of 30°.
Image scale is roughly 67 Km (about 42 miles) per pixel".
