The smooth ‘neck’ of Comet 67P/Churyumov–Gerasimenko was observed to undergo many changes throughout Rosetta’s mission. This particular set of images shows the appearance of scarp-like features in an originally featureless region, and which had completely disappeared after perihelion in August 2015.
The images were taken by Rosetta’s OSIRIS camera on 30 August 2014 (left), 22 January 2015 (middle) and 19 June 2016 (right), with resolutions of 1 m/pixel, 0.5 m/pixel and 0.5 m/pixel, respectively.
