North is up and East is to the left. The whitish object in the bottom right is an unrelated star in our own galaxy, less than 1000 light years away from Earth. Until our work, it was thought that all quasars were this colour. This picture was taken using the 2.3-metre telescope at Siding Spring Observatory. The colour picture was produced by combining separate blue, green and red images.
