Hapi Colors

Explanation: This false color image, made from data data acquired on 21 August 2014 by Rosetta's OSIRIS imaging system with broad-band filters centred at 989, 700, and 480 nanometers, shows the smooth Hapi region connecting the head and body of comet 67P/Churyumov-Gerasimenko. Differences in reflectivity have been enhanced in this image to emphasise the blueish colour of the Hapi region. By studying the reflectivity, clues to the local composition of the comet are revealed. Here, the blue colouring might point to the presence of frozen water ice at or just below the dusty surface.
