AstroPicture of the day: How the surface of a comet looks like

Rosetta is a robotic space probe built and launched by the European Space Agency to perform a detailed study of comet 67P/Churyumov–Gerasimenko – and here is how the surface of the comet actually looks like. The camera the shuttle used is greyscale, and researchers then used color filters to capture different spectrums of the light.
