Comet 67P/Churyumov-Gerasimenko was imaged on 14 July 2014 by OSIRIS, Rosetta’s scientific imaging system, from a distance of approximately 12 000 km. This image has been processed using ‘sub-sampling by interpolation’, a technique that removes the pixelisation and makes a smoother image. It does not, however, reveal hidden detail and it is therefore important to note that the comet’s surface is not very likely to be as smooth as the processing implies. The image suggests that the comet may consist of two parts: one segment seems to be rather elongated, while the other appears more bulbous.
