The results of red-shift surveys. (a) The first Center for Astrophysics slice, based on optical observations. Around the outside are markings indicating right ascension (in hours) of the galaxy.All of the galaxies in the indicated declination range, covering six degrees, are plotted in this single slice.The redshifts are plotted on the straight axis moving away from the point. (b) Two additional slices, showing different declination ranges. [John Huchra, CFA]
