The citing challenges long-held notions that supermassive galaxies formed over much longer periods of time.</p><p>“It is a bit like looking at rocks from the earliest times in Earth’s history and seeing fossils of fully formed animals,” said Pieter van Dokkum, the Sol Goldman Family Professor of Astronomy and professor of physics in Yale’s Faculty of Arts and Sciences.</p><p>According to a release, “The international team of researchers, led by scientists at the University of Geneva, identified the trio of early galaxies using data from the telescope’s FRESCO (First Reionization Epoch Spectroscopic Complete) Survey. FRESCO is able to accurately measure distances and masses of galaxies.”</p><div class="s2nPlayer k-iLgdKCFX" data-type="float" data-s2n-api="dfm_stn_player_script_id_iLgdKCFX"></div><script> function dfm_stn_player_script_id_iLgdKCFX( getS2NApiForPlayer ) { if( typeof window.MNGAuthentication !== 'undefined' ){ const s2nApi = getS2NApiForPlayer( document.querySelector('.k-iLgdKCFX') ); s2nApi.float = ! window.MNGAuthentication.isUserSubscriber(); } }</script><p>The galaxies have roughly the same number of stars as the Milky Way does today, according to a release. They are also forming new stars at a rate nearly twice as high as their lower-mass counterparts, as well as galaxies formed later on.</p><blockquote class="wp-embedded-content"
