Astronomers used to assume galaxies formed first and slowly grew the black holes at their centres. But JWST is now finding objects in the early universe where the black hole appears to have arrived first
Data from the James Webb Space Telescope (JWST) challenges established models of galactic evolution by revealing black holes existing before their host galaxies.
