An accidental discovery by a team of astronomers has upended existing theories about how galaxies formed in the early universe. The discovery, led by the "Cosmic Web" research group and international collaborators,
Astronomers have made an unexpected discovery of a massive galaxy, named JADES-GS-z14-0, that existed just 290 million years after the Big Bang, challenging existing models of the early universe. This galaxy, observed by the James Webb Space Telescope, appears to be much larger and more evolved than current theories predict for such an early time. It contains about 500 million stars and is actively forming new stars at a rate equivalent to the mass of the Sun every year. The galaxy's brightness and size suggest that either star formation was more efficient in the early universe or that the first stars formed much earlier than previously thought. This finding, presented at the 243rd meeting of the American Astronomical Society, indicates that the universe might have been capable of producing complex structures much sooner than anticipated, prompting a reevaluation of how galaxies form and evolve.
