The Nearest 15,000 Galaxies

  • The locations of the nearest 15,000 galaxies with known recessional velocity are displayed here on an Aitoff equal area grid in celestial coordinates, Right Ascension (R.A.) and Declination (Decl.).

  • All of these objects have measured recessional velocities less than 12,000 km/s.

  • The map is centered on R.A.= 6 hours, Decl. = 0 degrees.

  • The continous lines that rise diagonally through the center of the map show the locus in celestial coordinates of the lines of constant galactic latitude at -20deg, 0 and +20 deg. delineating the Zone of Avoidance, where distant galaxies are obscured at optical wavelengths by the dust and gas within the Milky Way.

  • The distribution of galaxies within this volume is not random; galaxies tend to cluster. Two major structures are easily seen:
