Enceladus (false-colors mosaic)
|
From afar, Enceladus exhibits a bizarre mixture of softened craters and complex, fractured terrains. This large mosaic of 21 narrow-angle camera images has been arranged to provide a full-disk view of the anti-Saturn hemisphere of Enceladus. This mosaic is a false-color view that includes images taken at wavelengths from the ultraviolet to the infrared portion of the spectrum and is similar to another, LR false-color view obtained during the flyby. In false-color, many long fractures on Enceladus exhibit a pronounced difference in color (represented here in blue) from the surrounding terrain. A leading explanation for the difference in color is that the walls of the fractures expose outcrops of coarse-grained ice that are free of the powdery surface materials that mantle flat-lying surfaces.
The original images in the false-color mosaic range in resolution from 350 to 67 mt per pixel (distance range from about 11.000 up to 61.000 Km).
