Icy cliffs in the Sun...

After journeying a bit more than an hour across the Solar System, bright Sunlight reflects off the gleaming icy cliffs in the wispy terrain of Dione and is captured by the Cassini spacecraft's cameras several light seconds later.
Saturn's Ring-Plane is here tilted slightly toward the Cassini spacecraft and is bisected by the Planet's dark shadow stretching across the Rings.
This view looks toward the Saturn-facing Hemisphere on Dione.

The image was taken in visible light with the Cassini spacecraft narrow-angle camera on Dec. 3, 2005, at a distance of approx. 2,8 MKM (about 1,7 MMs) from Dione and at a Sun-Dione-spacecraft, or phase, angle of 104°. Resolution in the original image was roughly 17 Km (such as about 11 miles) per pixel on Dione. The image has been magnified by a factor of two and contrast-enhanced to aid visibility".
