Fractured boulders on comet 67P/C-G
These two images, taken by Rosetta's OSIRIS narrow-angle camera, show two fractured boulders found on comet 67P/Churyumov-Gerasimenko in the Imhotep (left) and Atum (right) regions, respectively. Fracturing in the Imhotep boulder is so pervasive it has led to fragmentation of the 60 m-wide boulder.
An annotated version of the image with an indication of the physical scale is available here.
