  1. Jul 7, 2024 · According to data from the Hubble and James Webb Space Telescopes, the origins of the free-flying photons in the early cosmic dawn were small dwarf galaxies that flared to life, clearing the...

  2. Jun 19, 2024 · Astronomers discovered the first pair of merging quasars from the Cosmic Dawn, 900 million 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 24, 2024 · Cosmic dawn is the time encompassing the first billion years of the universe. Roughly 400 million years after the Big Bang, the Epoch of Reionization began, in which light from nascent stars...

  5. Jul 2, 2024 · 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.

  6. Jun 27, 2024 · The investigation constitutes the first mid-infrared study of a quasar that existed at cosmic dawn. The spectrum of light from this early supermassive black hole revealed the properties...

  7. Jun 19, 2024 · Cosmic dawn is the time encompassing the first billion years of the universe. During this period, roughly 400 million years after the Big Bang, the Epoch of Reionization began, in which light...
