The James Webb Space Telescope (JWST) has discovered MoM-z14, the most distant galaxy yet observed, existing just 280 million years after the Big Bang. Its redshift of 14.44 surpasses the previous record holder. This discovery, detailed in a preprint study, challenges existing theories about early galaxy formation. MoM-z14, though compact, exhibits rapid star formation and a composition similar to Milky Way globular clusters. Future telescopes like the Nancy Grace Roman Space Telescope are expected to uncover even more ancient galaxies.
