The James Webb Space Telescope (JWST) has discovered MoM-z14, the most distant galaxy ever observed, existing just 280 million years after the Big Bang. This discovery, confirmed through spectroscopy, pushes back the timeline of galaxy formation and challenges existing models. MoM-z14's existence suggests a far greater number of early galaxies than previously thought, impacting our understanding of dark matter and early universe processes. JWST's infrared capabilities, unlike Hubble's, allow observation of these distant, early galaxies.
