This image of the coma of comet 67P/Churyumov-Gerasimenko as seen with OSIRIS covers an area about 90 miles (150 kilometers) across. This image was taken on July 25, 2014 with an exposure time of 330 seconds. The hazy circular structure to the right and center of the coma is an artifact due to overexposure of the nucleus.

Rosetta is a European Space Agency mission with contributions from its member states and NASA. Rosetta's Philae lander is provided by a consortium led by the German Aerospace Center, Cologne; Max Planck Institute for Solar System Research, Gottingen; French National Space Agency, Paris; and the Italian Space Agency, Rome. JPL, a division of the California Institute of Technology, Pasadena, manages the U.S. participation in the Rosetta mission for NASA's Science Mission Directorate in Washington. Rosetta carries three NASA instruments in its 21-instrument payload.

OSIRIS was built by a consortium led by the Max Planck Institute for Solar System Research, Gottigen, Germany, in collaboration with the Center for Studies and Activities in Space, University of Padova, Italy; the Astrophysics Laboratory, Marseille, France; the Institute of Astrophysics of Andalusia, Spain; the Scientific Support Office of the European Space Agency, The Netherlands; the National Institute for Aerospace Technology, Torrejon de Ardoz, Spain; the Technical University of Madrid, Spain; the Department of Physics and Astronomy of Uppsala University, Sweden; and the Institute of Computer and Network Engineering of the Technical University, Braunschweig, Germany. OSIRIS was financially supported by the national funding agencies of the German Space Agency, Cologne, Germany; National Centre for Space Studies, Paris, France; Italian Space Agency, Rome; Ministry of Education and Science, Madrid, Spain; the Swedish National Space Board, Solna, Sweden; and the European Space Agency Technical Directorate, Paris, France.
