A team of astronomers, including one at the Johns Hopkins University, has uncovered a burgeoning galactic metropolis, the most distant known in the early universe. This ancient collection of galaxies presumably grew into a modern galaxy cluster similar to the massive ones seen today. The developing cluster, named COSMOS-AzTEC3, was discovered and characterized by multi-wavelength telescopes, including NASA’s Spitzer, Chandra and Hubble space telescopes, and the ground-based W.M. Keck Observatory and Japan’s Subaru Telescope. Johannes Staguhn, associate research scientist at Johns Hopkins University’s Center for Astrophysical Sciences in the Henry A. Rowland Department of Physics and Astronomy, contributed data to uncover the nature of a main cluster member.
