Webb Telescope Discovers Non-Rotating Giant Galaxy in Early Universe
Astronomers utilizing the James Webb Space Telescope have identified a massive galaxy, designated XMM-VID1-2075, that exhibits no rotation despite forming less than two billion years after the Big Bang. This discovery challenges prevailing cosmological theories, which posit that young galaxies should possess significant angular momentum from their formation, with non-rotating traits typically reserved for much older, evolved systems. Led by Ben Forrest of the University of California, Davis, the study published in Nature Astronomy reveals that this early universe galaxy contains several times more stars than the Milky Way and has ceased star formation. While current models suggest such 'slow rotators' result from billions of years of mergers, researchers hypothesize a single dramatic collision between oppositely spinning galaxies may have canceled out its motion. The team, part of the MAGAZ3NE survey, used Webb’s advanced capabilities to track internal stellar movements, finding strong random motion instead of spin. This finding prompts a reevaluation of galaxy formation timelines and encourages further searches for similar anomalies to test computer simulations regarding the frequency and evolution of non-rotating galaxies in the early cosmos.
