JWST beats its own record with potential most distant galaxies

Astronomers are now discovering record-breaking distant galaxies by the dozen while sifting through the treasure trove of data now being collected by the James Webb Space Telescope (JWST or Webb). Among them are several galaxies dating back to just over 200 million years after the Big Bang.

Prior to the launch of the James Webb Space Telescope, the most distant confirmed galaxy known was GN-z11, which astronomers saw as it was about 420 million years after the Big Bang, giving it what astronomers call a redshift of 11.6. (Redshift describes how much the light coming from a galaxy has been stretched as the universe expands. The higher the redshift, the farther back in time we see a galaxy.)
