False-color mosaic shows the entire hemisphere of Iapetus (1,468 km or 912 mi across) visible from the
Cassini orbiter on the outbound leg of its encounter with the two-toned
moon of Saturn in September 2007. The central
longitude of the trailing hemisphere is 24 degrees to the left of the image's center. It is hypothesized that the moon's
two-toned nature is due to the
sublimation of various ices
evaporated from the warmer parts of the surface.Photo credit:
