Anaglyph view looking on to the Aswan cliff in the Seth region of Comet 67P/Churyumov–Gerasimenko. Part of the comet’s ‘neck’ and ‘head’ can be seen in the foreground.
The image was taken on 19 September 2014, well before part of the cliff top fell away on 10 July 2015.
Anaglyph images like these were prepared to help evaluate the volume of overhang that detached. The images are best viewed using red–green/blue 3D glasses.
The image was taken by Rosetta’s OSIRIS camera, approximately 26 km from the surface of the comet. The image scale is 0.5 m/pixel. The Aswan cliff is approximately 134 m high.
