Local Group galaxy cluster, computer graphic. Some 40 galaxies of the central area of the Local Group are shown relative to our spiral Milky Way Galaxy (centre). The concentric circles are 1 million light years apart, and lines show the positions of galaxies above (green) or below (orange) the celestial equator. The radial lines show the directions in the sky. An inset (upper left) shows the galaxies within 500,000 light years of the Milky Way. The largest galaxies are the Milky Way and Andromeda (M31, upper right) and M33 (right of Andromeda). The inset includes the two satellite galaxies of the Milky Way, the Large and Small Magellanic Clouds (lower centre). For a labelled version of this graphic, see R900/091.
