Using the NASA/ESA James Webb Space Telescope, astronomers confirmed that supermassive black holes can starve their host galaxies when they run out of fuel to form new stars.
An international team, including the University of Cambridge, looked at a galaxy similar in size to the Milky Way from about two billion years after the Big Bang. This galaxy has a supermassive black hole in its center but is “dead” because it stopped making new stars.
