"Surprising Discoveries: Monster Stars and Supermassive Black Holes in Ancient Galaxies"

Astronomers using the James Webb space telescope have discovered a supermassive black hole at the heart of an ancient galaxy known as GS-9209, which is five times larger than expected for the number of stars it contains. The galaxy is one of the most distant to have been observed and recorded, lying 25bn light-years from Earth. The black hole is a "big surprise" and lends weight to the theory that such enormous black holes are responsible for shutting down star formation in early galaxies.
