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. The paper outlining this discovery was posted to the arXiv preprint server on Aug. 18.
JWST Discovers Luminous Galaxies in Early Universe Previously Misidentified as Quasars
A study using the James Webb Space Telescope has discovered that two early-universe objects previously thought to be faint quasars are actually luminous galaxies with intense star formation. This research, which highlights the existence of massive stars in the early universe, was published on August 18. The findings could have implications for understanding cosmic evolution and the universe's history, which may indirectly relate to Iran's scientific community's interests in astrophysics.
