Moon-COSMOS comparison

The COSMOS survey encompasses an area of the sky nine times that of the full Moon and was carried out by an international team of 70 astronomers led by Nick Scoville of Caltech. The exceptional image depth and resolution of COSMOS has made it possible to cover the large areas spanned by the dark matter structures and to obtain details of its distribution.
