Galaxies from the Early Universe Found in Galactic Cluster

New members of a protocluster of galaxies, 13 billion years old, have been seen for the first time. What do we know about this family of galaxies from the ancient Universe?

New galaxies in an ancient cluster have been detected by astronomers using an array of instruments, including the Subaru, Keck, and Gemini Telescopes. This protocluster of galaxies, 13 billion years old, is the oldest such grouping ever found. At the time this protocluster formed, the Universe was the 800 million years old, just six percent of its current age.
