This post is based on information provided by the OSIRIS team at the Max Planck Institute for Solar System Research (MPS) in Germany. If it could be seen with the naked human eye, the nucleus of #Comet_67P/Churyumov-Gerasimenko would be a dark grey all over. With its array of specialised filters, however, #Rosetta’s scientific imaging system OSIRIS can discern tiny differences in reflectivity at different wavelengths across the comet’s surface. In turn, these differences can reveal clues as to the local composition of the comet. The image shown here focuses on the Hapi region of the comet. Hapi is located in the neck between the comet’s two lobes and has in the past months proven to be particularly active, the source of many of the spectacular jets of dust and gas seen in the wider-view (...)
