Open in 3DWhat it is
A cluster of more than 150 galaxies round the ellipticals NGC 3309 and NGC 3311, in the Hydra–Centaurus Supercluster.
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.
