A2744z7p9OD is the highest redshift spectroscopically confirmed protocluster discovered to date.[when?] The cluster is located behind the Abell 2744 cluster at a redshift distance of z=7.88. It has a radius of 60 kiloparsecs and within that lies seven currently discovered galaxies making it an overdense region of galaxies. It lacks any strong confirmed Lyman-Alpha emissions.[1]
Theses protoclusters like A2744z7p9OD resemble what large clusters like the Coma cluster started out as, just with tens of galaxies instead of thousands of galaxies modern large clusters have. Theses clusters reveal how early clusters in the early universe evolved and changed over time.[2][3]
