Go Back

Half-phase Dione rotating (13-image animation) This animation consists of 13 images of Dione taken about twice per hour over a period of six hours. Over that time, Dione's "wispy terrain" -- now known to be networks of crisp fractures in Dione's icy crust -- passes from day into night, and the long shadows caused by the low sun at the dusk terminator trace the topography of the fractures.

Images were taken from 00:04:49 to 06:17:13.

Processing consisted of enlarging the original 512-pixel-square images by a factor of two, then of aligning and animating them.
