The structures and star populations of massive galaxies appear to change as they age, but much about how these galaxies formed and evolved remains mysterious. Many of the oldest and most massive galaxies reside in clusters, enormous structures where numerous galaxies are found concentrated together. Galaxy clusters in the early universe are thought to be key to understanding the lifecycles of old galaxies, but to date astronomers have located only a handful of these rare, distant structures. New research from a team led by Carnegie's Andrew Newman has confirmed the presence of an unusually distant galaxy cluster, JKCS 041. It is published in the Astrophysical Journal. read more
