 Searching through the ESA index (European Space Agency) I had a hard time finding anything. After about twenty large photos, I finally found something that I thought would be interesting to you. An ancient structure built upon the comet. This looks like a foundation, but its not, its a structure with many sections. This area of the comet is about 3km across, so that would mean this structure above is about 250 meters across.
