Saturn’s icy moon Dione has undoubtedly experienced geologic activity since its formation, as evidenced by the tectonic faults and craters on its surface.

To create this enhanced-color view, ultraviolet, green and infrared images were combined into a single black and white picture that isolates and maps regional color differences. This “color map” was then superposed over a clear-filter image. The origin of the color differences is not yet understood, but may be caused by subtle differences in the surface composition or the sizes of grains making up the icy soil.

This view looks toward the leading hemisphere on Dione.
