One pixel corresponds to approximately 37 meters. The bright neck region between the comet’s head and body is becoming more and more distinct.

New imagery of the nucleus of comet 67P/Churyumov-Gerasimernko as the European Space Agency’s Rosetta spacecraft pulls in closer to the target.According to a press statement from the Max Planck Institute for Solar System Research in Germany), the Imagery confirms the collar-like appearance of the neck region which presents itself brighter than most parts of the comet’s body and head. The reason for this feature is still subject to discussion. Possible explanations range from differences in material or grain size to topological effects.

Rosetta is an ESA mission with contributions from its member states and NASA.

Rosetta will be the first mission in history to rendezvous with a comet, escort it as it orbits the Sun, and deploy a lander to its surface.
