The colors of Comet Churyumov-Gerasimenko
Lindau, Germany (SPX) Nov 16, 2015
OSIRIS, the scientific imaging system of ESA's Rosetta mission to comet 67P/Churyumov-Gerasimenko, shows a surface with subtle, but significant color variations. To the naked eye comet 67P/Churyumov-Gerasimenko, destination and by now longtime companion of ESA's Rosetta spacecraft, is rather unremarkably colored: black as a piece of coal all over. However, with the help of OSIRIS, Rosetta's onboard scientific imaging system, scientists can make visible subtle, yet comprehensive differences in surf ... read more
