The "Young Face" of Enceladus

Original caption:"For Enceladus, wrinkles mean the opposite of old age. This view of a crescent Enceladus shows a transition zone between a wrinkled and presumably younger Region of terrain and an older, more heavily cratered Region. The moon's geologically active Southern Polar Region is seen on the left.
The lit terrain shown here is on the side of Enceladus that faces away from Saturn.

The image was taken in visible light with the Cassini spacecraft narrow-angle camera on Dec. 24, 2005 at a distance of approx. 108.000 Km (such as about 67.000 miles) from Enceladus, at a Sun-Enceladus-spacecraft angle of 102°.
Image scale is roughly 646 mt (about 2.118 feet) per pixel".
