The James Webb Space Telescope has identified XMM-VID1-2075, a galaxy with 330 billion solar masses that shows virtually no rotation despite existing just 1.8 billion years after the Big Bang — a state thought to require billions of years of galactic mergers. The finding, published in Nature Astronomy in May 2026, challenges models of how massive galaxies assemble and adds a new dimension to the ongoing "too big, too soon" tension between JWST observations and standard cosmology.
