ESA’s comet-chasing Rosetta mission spent much of the second half of October orbiting Comet 67P/Churyumov–Gerasimenko at less than 10 km from its surface. This selection of previously unpublished ‘beauty shots’, taken by Rosetta’s navigation camera, presents the varied and dramatic terrain of this mysterious world from this close orbit phase of the mission. Some light contrast enhancements have been made to emphasise certain features and to bring out features in the shadowed areas. In reality, the comet is extremely dark -– blacker than coal. The images, taken in black-and-white, are grey-scaled according to the relative brightness of the features observed, which depends on local illumination conditions, surface characteristics and composition of the given area. Some slight vignetting can also be seen in the corners of some images.

Tschurjumow-GerassimenkoTschurjumow-Gerassimenko (dt.), offizieller Name 67P/Churyumov-Gerasimenko, von Forschern und seit Mitte 2014 auch von den Medien oft Tschuri genannt, ist ein kurzperiodischer Komet. Er ist der erste Komet, den eine Raumsonde begleitet hat, und der erste, auf dem ein Lander niederging. Die Ergebnisse der Mission sind in vieler Hinsicht überraschend, insbesondere die unregelmäßige Gestalt, die hohe mittlere Dichte und die abwechslungsreichen Strukturen der Oberfläche: felshartes Eis mit hohem mineralischem Anteil, fast durchweg bedeckt mit Schotter und lockerem, zum Teil polymerem organischem Material. .. weiterlesen
