  1. Jun 19, 2024 · Astronomers discovered the first pair of merging quasars from the Cosmic Dawn, 900 million years after the Big Bang.

  2. 4 days ago · Elevated UV luminosity density at Cosmic Dawn explained by non-evolving, weakly-mass dependent star formation efficiency. Recent observations with the James Webb Space Telescope (JWST) have uncovered unexpectedly high cosmic star formation activity in the early Universe, mere hundreds of millions of years after the Big Bang.

  3. Jun 25, 2024 · Using the James Webb Space Telescope (JWST), astronomers have spotted a supermassive black hole at "cosmic dawn" that seems to be impossibly massive.

  4. Jun 22, 2024 · Since the James Webb Space Telescope began operating two years ago, astronomers have been using it to leapfrog one another millions of years into the past, back toward the moment they call cosmic dawn, when the first stars and galaxies were formed.

  5. Jun 18, 2024 · A double quasar spiraling toward a great merger has been discovered lighting up the "cosmic dawn," just 900 million years after the Big Bang. They are the first quasar pair spotted that far...
