Crooked Shadow (Natural Colors; credits: Lunexit)

Caption NASA:"The shadow of the moon Mimas strikes the F-Ring at a different angle than the angle at which it is cast on the A-Ring, illustrating differences in the vertical heights of the Rings in this image taken as Saturn approaches its August 2009 Equinox.

The novel illumination geometry that accompanies Equinox lowers the Sun's angle to the Ring-Plane and causes out-of-plane structures to cast long shadows across the Rings. These scenes are possible only during the few months before and after Saturn's Equinox, which occurs only once in about 15 Earth years. To learn more about this special time and to see movies of moons' shadows moving across the Rings, see PIA11651 and PIA11660.

Pan (about 28 Km, or approx. 17 miles across) orbits in the Encke Gap and is visible on the left of the image. The brightness in the lower left of the image is lens flare, a radially extending artifact that results from light being scattered within the camera optics. The shadow of Saturn cuts across the lower right of the image. Two stars can be seen through the Rings. Other bright spots in this image are also background stars.

This view looks toward the unilluminated side of the Rings from about 52° above the Ring-Plane. The image was taken in Visible Light with the Cassini Spacecraft wide-angle camera on June 15, 2009. The view was obtained at a distance of approx. 1,8 MKM (about 1,1 MMs) from Saturn and at a Sun-Saturn-Spacecraft, or Phase, angle of 90°. Image scale is roughly 103 Km (about 64 miles) per pixel".
