Using the Subaru Telescope, a team of astronomers led by Jun Toshikawa (The Graduate University for Advanced Studies, Japan), Dr. Nobunari Kashikawa (National Astronomical Observatory of Japan), and Dr. Kazuaki Ota (Kyoto University) has discovered the most distant protocluster of galaxies ever found--one that existed less than one billion years after the Big Bang. Since protoclusters are ancestors of today's massive clusters of galaxies, this discovery of a protocluster in the early Universe advances our understanding of how large-scale structures form and how galaxies evolve.
