The active South Pole of Enceladus

Caption NASA originale:"The wrinkled border of Enceladus' South Polar Region snakes across this view, separating fresher, younger terrain from more ancient, cratered provinces.
This is the Region of Enceladus that is known to be presently geologically active. At right are clearly visible ridges and troughs thought to be caused (probably) by compressional stresses across the icy surface.

The image was taken in polarized green light with the Cassini spacecraft narrow-angle camera on Sept. 9, 2006 at a distance of approx. 66.000 Km (such as about 41.000 miles) from Enceladus and at a Sun-Enceladus-spacecraft, or phase, angle of 104°. Image scale is roughly 396 mt (about 1.300 feet) per pixel".
