A short-lived outburst from comet 67P/Churyumov-Gerasimenko was captured by Rosetta's OSIRIS narrow-angle camera on July 29, 2015. The image at left was taken at 13:06 Greenwich Mean Time (GMT) (6:06 a.m. PDT), and does not show any visible signs of the jet. It is very strong in the middle image captured at 13:24 GMT (6:24 a.m. PDT). Residual traces of activity are only very faintly visible in the final image taken at 13:42 GMT (6:42 a.m. PDT).
The images were taken from a distance of 116 miles (186 kilometers) from the center of the comet. The jet is estimated to have a minimum speed of 33 feet per second (10 meters per second) and originates from a location on the comet's neck.
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. NASA's Jet Propulsion Laboratory, 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.
