superclusters rule the tiny collection of galaxies

The cosmic bullies next door How vast superclusters rule the tiny collection of galaxies we call the Local Group  by Liz Kruesi IN 1994 astronomer Renée Kraan-Korteweg spotted some 600 galaxies lying the same distance away from us, all clustered around the constellations Hydra and Vela. These findings hinted that the region might harbor an enormous structure, perhaps a supercluster, though learning more about it would not be easy. These galaxies sit behind the Milky Way’s dense disk, which holds billions of stars and enormous clouds of dust, materials that obscure background light signals. To study what lies behind this region, aptly

supercluster Super rich Galactic Cluster

Super-rich Galactic Cluster This new image from the NASA/ESA Hubble Space Telescope shows the super-rich galaxy cluster Abell 1413. Located between the constellations of Leo (The Lion) and Coma Berenices, the cluster is over 2 billion light-years from Earth. This image is dominated by a large and highly elliptical galaxy called MCG+04-28-097, with a halo of stars extending for more than 6.5 million light-years. Abell 1413 is part of the Abell catalog, a collection of over 4000 rich clusters of galaxies fairly close to Earth — at least from a cosmological perspective — their light took less than 3 billion
