Many of the images we’ve been seeing of the craggy surface of comet 67P/Churyumov-Gerasimenko, as incredible as they are, are still monochrome. Now Rosetta’s OSIRIS team has released a true-color image of the comet taken with it high-res science imaging instrument… but even then it’s still pretty much grey. “As it turns out, 67P/C-G looks dark grey, […]

Many of the images we’ve been seeing of the craggy surface of comet 67P/Churyumov-Gerasimenko, as incredible as they are, are still monochrome. Now Rosetta’s OSIRIS team has released a true-color image of the comet taken with it high-res science imaging instrument… but even then it’s still pretty much grey.

“As it turns out, 67P/C-G looks dark grey, in reality almost as black as coal,” said OSIRIS Principal Investigator Holger Sierks from the Max Planck Institute for Solar System Research (MPS).
According to a post on the Rosetta blog:
Long before Rosetta’s arrival at the comet, ground-based telescope observations had shown 67P/C-G to be grey on average, but it was not possible to resolve the comet and see any surface details. However, now that OSIRIS is able to take images from ...
