The James Webb Space Telescope has identified the most distant galaxy, MoM z14, existing just 280 million years post-Big Bang, surpassing the previous record holder, JADES-GS-z14-0, by 20 million years. MoM z14 is approximately 50 times smaller than the Milky Way and shows unusual emission lines, indicating a young galaxy with a rapid star formation rate and a surprising lack of surrounding neutral hydrogen gas. The presence of carbon and nitrogen suggests that earlier galaxies may exist, as the first galaxies were composed primarily of hydrogen and helium.
