Scientists Discover Most Distant Lyman-Continuum-Emitting Galaxy, LCEz4-M1

Astronomers have identified LCEz4-M1, the most distant Lyman-continuum-emitting galaxy known to date, at a redshift of z=4.444 in the Hubble Ultra Deep Field. This discovery, made using data from the Hubble Space Telescope, James Webb Space Telescope, and ESO's Very Large Telescope, provides critical evidence for how early galaxies emitted ionizing photons and contributed to the cosmic reionization period, just 420 million years after the Big Bang.
