JWST spots the universe’s most distant galaxy MoM-z14, challenging early-universe predictions
TL;DR
NASA’s James Webb Space Telescope has detected MoM-z14, the farthest galaxy observed to date, about 13.5 billion years back (roughly 280 million years after the Big Bang). The galaxy is brighter, more compact, and chemically enriched than expected for such an early epoch, challenging existing models of early star and galaxy formation and suggesting the early universe may have evolved more rapidly than theories predicted.
