The “dark sides” of celestial bodies are pretty interesting to look at and this is not exception. The ESA’s Rosetta craft took this rare picture of the dark side of comet 67P/Churyumov-Gerasimenk which it has been circling for the upcoming rendezvous with its Philae lander. Rosetta’s scientific imaging system (OSIRIS) snapped this picture in September, at a distance of just 19 kilometers from the comet and gives us some indications of surface structures.
