"James Webb Telescope Discovers Oldest 'Dead' Galaxy, Challenging Cosmology"
The James Webb Space Telescope (JWST) has observed a young galaxy, JADES-GS-z7-01-QU, that recently exited a major star-forming epoch, raising the question of whether such galaxies are permanently "dead" or if star-formation will reawaken. The observations shed light on the transition of galaxies from active star-forming phases to passive phases, and whether star-formation episodes are temporary or permanent. JWST's observations of early, low-mass galaxies will provide insights into the evolution of the Universe.
