Rhea (false colors)

Caption NASA originale:"This false-color picture of Saturn's moon Rhea from Cassini enhances slight differences in natural color across the moon's face. The extreme north and south latitudes have a notable difference in hue compared to the mid-latitudes.
This view of Rhea is a composite of images taken using filters sensitive to green (centered at 568 nnmts) and infrared light (2 infrared filters, centered at 752 and 930 nnmts) and has been processed to accentuate subtle color differences.
The image was taken with the Cassini spacecraft narrow angle-camera on Feb. 18, 2005, at a distance of approximately 890.000 Km from Rhea and at a Sun-Rhea-spacecraft phase angle of 116°. The image scale is 5 Km per pixel".
