This image showcases changes identified in high-resolution images of Comet 67P/Churyumov-Gerasimenko during more than two years of monitoring by ESA's Rosetta spacecraft.

This image showcases changes identified in high-resolution images of Comet 67P/Churyumov-Gerasimenko during more than two years of monitoring by ESA's Rosetta spacecraft.

The approximate locations of each feature are marked on the central context images. Dates of when the before and after images were taken are also indicated. Note that the orientation and resolution between image pairs may vary, therefore set arrows in each image point to the location of the changes, for guidance.

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.
