Aten–Babi boundary

This image is a crop from an OSIRIS narrow-angle camera image taken on 11 September 2014 from a distance of about 27 km from the comet surface. The image focuses on the contrast of surface materials between the Aten depression (top) and the smooth dust covering in Babi (bottom).
