James Webb Space Telescope observed a galaxy in a particularly young stage of the universe.
The light from the galaxy called J1120+0641 took almost as long to reach Earth as the universe has taken to develop to the present day .
It is inexplicable how the black hole at its center could have weighed over a billion solar masses back then, as independent measurements have shown.
J1120+0641 is no different from quasars at later times.
The torus and feeding mechanism in this very early quasar appear to be the same as for its modern counterparts.
The only difference is a somewhat higher dust temperature around a hundred Kelvin warmer than the 1300 K found for the hottest dust in less distant quasar.
The results support the idea that supermassive black holes started out with considerable masses from the get-go.
