A deliberately saturated version of this image to bring out details in a shadowed region of Comet 67P/Churyumov-Gerasimenko. The image was taken on 30 October 2014 by Rosetta’s OSIRIS scientific imaging system from a distance of approximately 30 kilometres. At this distance, the image scale is approximately 0.5 metres/pixel, so the image measures about 1.1 km across.
