For decades, astronomers have debated a fundamental question about the cosmos: which came first, the supermassive black hole or the galaxy that hosts it? The conventional model suggested that galaxies formed first, and the black holes at their centers grew gradually alongside them. New observations from the James Webb Space Telescope (JWST) have now provided a definitive and surprising answer. In two separate landmark studies, JWST data reveal that in the early universe, some black holes were already enormous when their host galaxies were still in their infancy—and in at least one case, the black hole appears to have gotten there first.
A Black Hole That Formed Before Its Galaxy
The first major discovery centers on a "Little Red Dot" galaxy cataloged as Abell2744-QSO1, or QSO1, seen as it was just 700 million years after the Big Bang. Using Webb's powerful NIRSpec instrument, a research team confirmed that QSO1 harbors a supermassive black hole clocking in at around 40 million times the mass of our Sun. The critical finding is not just its size, but its timing: the data indicates this black hole had already formed before the galaxy around it had assembled the bulk of its stars .

These findings suggest supermassive black holes were not just passengers in galaxy formation, but primary drivers that may have seeded their own galaxies and shaped their evolution from the very beginning.
This is the most direct evidence to date that the answer to the cosmic chicken-and-egg problem is the egg—the black hole came first. This flips the standard picture of galaxy-led co-evolution on its head. The research, published in May 2026, suggests that instead of forming passively inside a pre-existing galaxy, such enormous black holes may have formed through the direct collapse of massive gas clouds, creating a gravitational anchor that then pulled in more gas and dust to build the galaxy around it . As the NASA team concluded, some supermassive black holes were "enormous from the beginning, forming without a stellar collapse phase, and without a significantly more massive host galaxy to feed them" .
An Overmassive Black Hole Growing in Fast-Forward
The second discovery, published in Nature Communications in November 2025, tackles the problem of black hole growth rates. Using JWST, researchers confirmed an actively accreting supermassive black hole at the center of a galaxy called CANUCS-LRD-z8.6, which existed just 570 million years after the Big Bang. This black hole is spectacularly out of balance with its host. In the nearby, modern universe, a galaxy's central black hole maintains a predictable mass ratio with its galaxy's central bulge of stars. The black hole in CANUCS-LRD-z8.6 shatters that relationship—it is vastly more massive than it should be for its tiny host galaxy, a state astronomers call "overmassive" .
The ESA describes it as a "greedy" black hole growing at an exceptionally rapid rate, far outpacing the growth of the galaxy around it. This hyperactive feeding indicates that in the first billion years of the universe, black holes were governed by different growth mechanisms that allowed them to bulk up at an accelerated pace, even within small, chemically immature galaxies . This directly connects the mysterious "Little Red Dots" observed by JWST to the luminous quasars we see shining across cosmic time.
Rewriting the Rules of Cosmic Evolution
Together, these two discoveries paint a new and more active picture of the early universe. They reveal that supermassive black holes were not passive passengers, but likely played a primary role in sculpting the very first galaxies.
Black holes as galaxy seeds: The QSO1 finding provides the strongest evidence yet that supermassive black holes can act as the seeds around which galaxies subsequently assemble, rather than being a consequence of galaxy formation .
A broken mass relationship: The CANUCS-LRD-z8.6 result confirms that the tight black-hole-to-galaxy mass relation we see in the local universe did not apply to the first generation of black holes, which grew far more efficiently .
Galaxy-shaping feedback from the start: The intense radiation and powerful outflows produced by these early, rapidly growing black holes would have heated and expelled surrounding gas, directly regulating star formation and determining the final size and shape of their host galaxies .
These JWST observations don't just answer old questions—they open new ones about the exact physics that allowed direct-collapse black holes to form and power such rapid growth. As one research team noted, they represent a "complete paradigm shift in our understanding of how black holes grow" . The cosmos just got a little younger, and its first architects a lot more powerful.
