NASA’s James Webb Space Telescope (JWST) has uncovered startling evidence of dense galaxies actively shaping the early universe by carving out vast cosmic bubbles, according to new data from its first science observations. These massive galaxy clusters, detected at redshifts above z=8—meaning they formed just 600 million years after the Big Bang—are disrupting the intergalactic medium with intense radiation and stellar winds.
Emma Thompson at the University of California, Berkeley, and Dr. Rajiv Mehta at the European Space Agency's Astrophysics Division have identified these structures as key agents in reionizing the universe, a pivotal phase when neutral hydrogen was ionized, allowing light to travel freely. The full version stays on the original page, which this listing opens directly.
