Webb Discovers Ultra-Early Galaxy MoM-z14 That Challenges Early-Universe Theories
TL;DR Summary
NASA's James Webb Space Telescope identified the galaxy MoM-z14 as it appeared about 280 million years after the Big Bang (redshift 14.44), meaning light has traveled roughly 13.5 billion years. Its brightness and nitrogen enrichment exceed predictions for such an early object, challenging current models and hinting at new physics or star-formation pathways during the epoch of reionization; follow-up spectroscopy is needed to confirm details and refine our picture of the early Universe.
