In this groundbreaking discovery, the James Webb Space Telescope has identified a galaxy that stopped forming stars just over a billion years after the Big Bang. This rare and remarkable find, named GS-9209, offers valuable insight into the life cycle of galaxies and their mysterious endings. Astronomers believe the sudden halt in star formation was caused by an actively feeding black hole, which heated up nearby gas and prevented it from forming new stars. This discovery sheds new light on the process of galaxy evolution and the crucial role that black holes play in their ultimate demise.
