Dune-like structures

Evidence of dune-like structures in the surface dust of Comet 67P/Churyumov–Gerasimenko. Features like this may be the result of localised gas-driven transport of surface dust. The image was taken by the OSIRIS narrow-angle camera on 23 August 2014.

A labelled version of this image is available here.
