JWST breaks its own record for potential most distant galaxies

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

Before the launch of The James Webb Space Telescopethe most distant confirmed galaxy known was GN-z11which astronomers saw as it was about 420 million years after The big bangand gives it what astronomers call a redshift of 11.6. (Redshift describes how much the light coming from a galaxy has been stretched as univers expands. The higher the redshift, the further back in time we see a galaxy.)
