This is a picture of comet 67P/Churymov-Gerasimenko in the constellation Ophiuchus. The image was taken on March 21, 2014, by the narrow-angle camera of the Rosetta spacecraft's Optical, Spectroscopic and Infrared Remote Imaging System (OSIRIS). The comet is indicated by the small circle next to the bright globular star cluster M107. The image was taken from a distance of about 3 million miles (5 million kilometers).
