Images of Pluto’s surface synthesized from Hubble photos

New images showing the surface of the dwarf planet Pluto have been released. The images were created from photographs taken by the NASA Hubble Space Telescope over a period of a year. According to the HubbleSite News article, a superresolution technique is used on "multiple, slightly offset pictures" of a few pixels wide to "synthesize a higher-resolution view". The process is achieved over four years with 20 computers operating concurrently.
