The two large galaxies at the center of the cluster are giant ellipticals, namely NGC 4889 and NGC 4874 to its right.
Located about 321 million light-years away from us in the constellation of Coma Berenices, the Coma galaxy cluster has made a significant mark in our study of. In 1937, it was within this cluster where Caltech astronomer Fritz Zwicky first found evidence for the existence of dark matter. He noticed that the galaxies in the cluster were moving faster than thegenerated by all the cluster's visible matter should allow.
Another filament is found connecting the north-east corner of the Coma Cluster and is associated with the small group of galaxies that surrounds the giant, which is currently falling into the cluster. In particular, this filament is bringing in pristine, cold hydrogen gas that is sparking fresh star formation in that corner of the cluster. It also shows that the Coma Cluster is still accreting matter and growing in mass via these filaments.
Despite its name, the Dark Energy Camera that produced this shot of the Coma Cluster has since retired from duties scrutinizing dark energy, following its stint leading the Dark Energy Survey between 2013 and 2019. Now, the 570-megapixel astronomical camera has become a general workhorse, routinely producing incredible images — including this one.
