The James Webb Space Telescope has spotted the earliest known galaxy to ever be"quenched" — suddenly and mysteriously halting its star formation — and scientists think the supermassive black hole in its center could be to blame.

The $10 billion space observatory was designed to read the earliest chapters of the universe's history in its faintest glimmers of light — picked up by the telescope’s infrared sensors — after being stretched out from billions of years of travel across the expanding fabric of space-time. Studying GS-9209 with the JWST revealed that the distant galaxy roared into life 600 million years after the Big Bang with an enormous burst of star formation.
"Typically, the galaxies we see today have had access to about five times as much gas or more than they formed stars. This result and some others are beginning to point now to that ratio being a bit higher in the early universe," Carnall said."The emerging picture is that at the highest redshifts [the furthest back in time] galaxies are capable of forming more of the available gas into stars.
