Comet 67P/C-G on 30 April 2014
Comet 67P/Churyumov–Gerasimenko seen towards the constellation of Ophiuchus (note that from the vantage point of Earth, both the comet and Rosetta are presently in Sagittarius), with the globular cluster M107 also clearly visible in the field of view. The image was taken on 30 April 2014 by the OSIRIS Narrow Angle Camera and the comet is already displaying a coma, which extends over 1300 km from the nucleus.
More images of comet 67P/Churyumov-Gerasimenko can be found in the '67P - by Rosetta' collection.
