James Webb uncovers the universe's largest, most detailed map of the cosmic web

Using JWST’s COSMOS-Web survey, astronomers mapped about 164,000 galaxies over a 255‑hour program to produce the largest, most detailed view of the cosmic web. The map shows how dense regions foster early galaxy growth and eventually quench star formation, revealing the large-scale structure of the universe up to redshift z~7 and refining our understanding of cosmic evolution since the universe’s infancy.
