Target: Comet 67P/Churyumov-Gerasimenko
Feature: Comet 67P/Churyumov-Gerasimenko, 329km from nucleus
"Enhanced NAVCAM image of Comet 67P/C-G taken on 27 March 2016, 329 km from the comet nucleus. In February and March, Rosetta spent several weeks at very close distances from the comet nucleus, which overfilled the field of view of the NAVCAM, providing us with striking views of the surface. During the current excursion, instead, we can enjoy again a view of the full nucleus and the environment around it.
In this CometWatch image, the small comet lobe is on the left and the large one on the right. The image was taken at a very large phase angle of about 159 degrees, meaning that the comet lies between the spacecraft and the Sun, and that all three are very close to being on the same line.
In this configuration, the nucleus appears backlit, with only a few portions of the illuminated surface visible from this view – in the upper and upper right part of the nucleus.
Thanks to the combination of a long, four-second exposure, no attenuation filter and a low-gain setting on the analogue signal processor of NAVCAM (a setting that is used to image bright targets), the image reveals the bright environment of the comet, displaying beautiful outflows of activity streaming away from the nucleus in various directions."
