Famous Places - Abell Clusters

The Abell Catalog of Galaxy Clusters was published in 1957 by American Astronomer George Abell. Abell used plates from the Palomar Observatory Sky Survey (POSS) to identify 2,712 galaxy clusters. Of these clusters, 509 have been observed by the SDSS. Most of the clusters in the Clusters Famous Places pages are Abell Clusters; six more are shown below. In each image, the largest galaxies belong to the Abell cluster. The clusters are listed in order of increasing redshift. Click one of the SDSS images to see the object in the Navigation tool.
