Coma Cluster

A rich cluster of more than 1,000 galaxies. In 1933 Fritz Zwicky found its galaxies moving too fast for the matter that can be seen: the first sign of dark matter.

Placed by its redshift, at the distance the expansion has carried it to by now; the dots around it are galaxies of the 2MASS and SDSS surveys, placed the same way.
