Galaxies in the newly identified protoclusters are surprisingly sparse and dim, which may be why they have been so difficult to find until now. The work was published June 15 in <a href="https://www.nature.com/articles/s41586-022-04681-6">Nature</a>. </span></span></span></span></span></span></span></span></p> June 22, 2022 - 10:13am Andy Fell /blog/long-ago-far-away-and-hard-see /news/astronomers-find-cosmic-titan-early-universe <p>An international team of astronomers has discovered a titanic structure in the early universe, just 2 billion years after the Big Bang. This galaxy proto-supercluster, nicknamed Hyperion, is the largest and most massive structure yet found at such a remote time and distance.</p> October 17, 2018 - 8:55am Andy Fell /news/astronomers-find-cosmic-titan-early-universe
