Using the James Webb Space Telescope (JWST), postdoc Rohan Naidu and his colleagues will be using a giant cluster of galaxies to “gravitationally magnify the light of some smaller objects up to 750 million years after the big bang,” reports Jonathan O’Callaghan for Scientific American. “The goal is to look for clumps of primordial gas, which could contain clusters of Population III stars—the first stellar generation thought to have lit up the universe,” writes O’Callaghan.
