A new study finds that two early-universe objects thought to be faint quasars are actually extraordinarily luminous galaxies powered by bursts of star formation. James Webb Space Telescope observations of the galaxies, seen when the universe was less than a billion years old, reveal signatures of extremely massive stars, including some potentially more than 200 times the mass of the sun.
