Japetus, from far away... (Natural Colors; credits: Lunexit)

Caption NASA:"A crescent Japetus shows, at the top right of this image, some of the dark terrain characterizing this unusual Saturnian moon.
Scientists continue to investigate the nature of the moon's surface.
Lit Terrain seen here is on the Saturn-facing side of Japetus (about 1471 KM, or approx. 914 miles across). North on Japetus is up and rotated 5° to the left.

Scale in the original image was 7 Km (about 4,5 miles) per pixel. The image has been magnified by a factor of two and contrast-enhanced to aid visibility.The image was taken in Visible Green Light with the Cassini Spacecraft narrow-angle camera on Sept. 11, 2009.
The view was acquired at a distance of approx. 1,2 MKM (about 746.000 miles) from Japetus and at Phase Angle of 125°".
