Cube of Spacetime (IMAGE)
Caption
This is a map of the cube of spacetime covered in the new survey, showing the 'lookback time' to the galaxies in billions of years. The positions of the 4,000 galaxies appear as circles. The colours represent the degree of redshift seen, with the bluer circles indicating galaxies seen in the more recent past, and so less redshifted. Green, yellow, orange and red circles indicate successively higher redshifts, and galaxies that are progressively seen further back in time.
