The treasure trove of early data from the James Webb Space Telescope has unearthed the most distant galaxies ever seen.
to detect 88 candidate galaxies beyond a redshift of 11, including a handful estimated to be at a redshift of 20. If validated, these galaxies would be, by far, the most distant ever detected. Because of cosmic expansion, today these galaxies would be over 35 billion light-years away from us.
One team of astronomers, led by Ph.D. student Callum Donnan of the University of Edinburgh, found a candidate galaxy at a redshift of 16.7, which equates to just 250 million years after the Big Bang.
In their paper, Donnan's team calculate the"galaxy ultraviolet luminosity function" between redshifts of 8 and 15. This function is an average of the amount of ultraviolet light associated with galaxies at any particular epoch. The value is strongly tied to star formation, because the more hot young stars are being formed in a galaxy, the more ultraviolet light it emits.
