James Webb Discovers Earliest Galaxy 280 Million Years After Big Bang

NASA's James Webb Space Telescope (JWST) has discovered the earliest and most distant galaxy ever observed, named MoM z14, which existed just 280 million years after the Big Bang, surpassing the previous record by 20 million years. This galaxy, about 50 times smaller than the Milky Way, shows emission lines indicating the presence of carbon and nitrogen, suggesting it is part of a later wave of galaxy formation and implying even earlier galaxies remain to be discovered. The discovery challenges previous expectations, as JWST has identified over 100 bright early galaxies, pushing the boundaries of our understanding of cosmic evolution. Additionally, JWST's advanced observations have revealed numerous early galaxy groups dating back twelve billion years, indicating that large-scale cosmic structures formed much earlier than previously thought. These findings collectively signify a revolution in cosmology, with JWST continuously unveiling new insights into the universe's origins and evolution. Researchers express optimism that future JWST data will uncover even earlier galaxies and further reshape our knowledge of the early universe.
