Enceladus

Caption NASA:"Few large craters are to be found in the wrinkled terrain of Enceladus, where the surface has been reworked by geologic processes presumably resulting from the moon's inner warmth.

Cassini spied the bright crescent of Enceladus on July 23, 2006 at a distance of approx. 628.000 Km (about 391.000 miles).
The image was taken in visible light with the Cassini spacecraft narrow-angle camera at a Sun-Enceladus-spacecraft, or phase, angle of 103°. Image scale is roughly 4 Km (about 2 miles) per pixel".
