"The [energy released from gas falling into the] the supermassive black hole is removing large amounts of gas very fast from the galaxy," D'Eugenio explained. "Without this gas, no new stars can be formed, so this galaxy is losing the `shine' of young and bright stars, and has already started it's long history of fading."

Astronomers using the James Webb Space Telescope (JWST) have spotted a huge black hole that is "starving" its host galaxy to death. GS-10578, more colloquially known as 'Pablo's Galaxy', is a large galaxy nearly 12 billion light-years away and has been known to be unusually 'dead' by astronomers for a while,
