The Cliffs of Comet Churyumov Gerasimenko

I can’t stop looking at this photograph. These kilometre high cliffs are part of the nucleus of the comet 67P/Churyumov Gerasimenko, as observed by the Rosetta spacecraft. I think it’s because I didn’t expect to see such details on a comet – plains, cliffs, boulders… it’s like earth, but very alien. There’s something awe-inspiring about it, these mountain walls on a far off comet.
