Gibbous Rhea (natural colors; credits: Lunexit)

Caption NASA (relativa al frame di Sx):"Bright, wispy markings cover the Trailing Hemisphere of Rhea. The features are thought to be similar in nature to the bright, icy canyons seen on Dione.
North on Rhea is up and rotated 17° to the left.

The image was taken in visible green light with the Cassini spacecraft narrow-angle camera on July 22, 2007. The view was acquired at a distance of approx. 1,2 MKM (about 700.000 miles) from Rhea and at a Sun-Rhea-spacecraft, or phase, angle of 42°.
Image scale is roughly 7 Km (approx. 4 miles) per pixel".
