DECam Zooms in on Antlia Galaxy Cluster

The Antlia galaxy cluster is a group of at least 230 galaxies held together by gravity; this cluster is unusual — unlike most other galaxy clusters, it appears to have no dominant galaxy within it.

The Antlia cluster is dominated by two massive elliptical galaxies: NGC 3268 (center) and NGC 3258 (lower right). Image credit: Dark Energy Survey / DOE / FNAL / DECam / CTIO / NOIRLab / NSF / AURA / R. Colombari & M. Zamani, NSF’s NOIRLab.
