Discoveries keep pouring out of the James Webb Space Telescope (JWST). Researchers observed an unusual cluster, which they dubbed the Infinity Galaxy. It appears to support a leading theory on how some supermassive black holes form.

But in the past two decades, new types of black holes have been seen and astronomers are beginning to understand how they form. Called supermassive black holes, they have been found at the center of pretty much every galaxy and are a hundred thousand to a billion times the mass of our sun.

"Theories involving substantial formation of stars prior to or together with the black hole formation and growth are very unlikely."
