False-colour image of the Hapi region on 67P
False colour image of the Hapi region on Comet 67P / Churyumov-Gerasimenko. This region connects the ‘head’ and ‘body’ of the comet. In this image, the differences in reflectivity have been increased to emphasise the bluish coloration of this region. Knowledge about the reflectivity is key to determining the surface composition. The bluish coloration indicates the presence of water ice on or directly beneath the dusty surface. The data used to create this image were acquired on 21 August 2014 with the Optical, Spectroscopic and Infrared Remote Imaging System (OSIRIS) on board Rosetta. The spacecraft was 70 kilometres away from the comet during data acquisition.
