The James Webb Space Telescope (JWST) has discovered ancient galaxy groups in regions of the observable universe previously deemed empty—just one billion years after the Big Bang. This revelation challenges existing models of cosmic evolution. Massive Survey Reveals Thousands of Ancient Clusters Researchers utilized the COSMOS-Web program—JWST’s most extensive sky-survey project. It captures light that traveled over 12 billion years, acting as a cosmic time machine into the formation of early cosmic structures. AMICO Algorithm Detects Nearly 1,700 Proto-Clusters Using the AMICO algorithm, astronomers detected 1,678 galaxy-group candidates, with over 670 confirmed with 90 percent confidence—and an additional 850 verified via spectroscopy.
