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).
ESA member states and NASA contributed to the Rosetta mission. Airbus Defense and Space built the Rosetta spacecraft. JPL manages the US contribution of the Rosetta mission for NASA's Science Mission Directorate in Washington. JPL also built the Microwave Instrument for the Rosetta Orbiter and hosts its principal investigator, Samuel Gulkis. The Southwest Research Institute in San Antonio developed the Rosetta orbiter's Ion and Electron Sensor (IES) and hosts its principal investigator, James Burch. The Southwest Research Institute in Boulder, Colo., developed the Alice instrument and hosts its principal investigator, Alan Stern.
