JWST Finds a New Class of Object at Cosmic Dawn: The 'Black Hole Star'

A team led by Rohan Naidu of the University of Hawaii has identified what they're calling a brand-new type of astrophysical object, and the catch is that it doesn't fit cleanly into any category astronomers had before.

<cite index="13-5,13-6">Astronomers announced Wednesday they had discovered a new type of astronomical object called a 'black hole star,' potentially solving a mystery involving strange red dots spotted in the early universe. The object looks like a star the size of our solar system, but produces 100 billion times more energy than any star.</cite> That energy output isn't consistent with stellar physics. It's consistent with a black hole.

<cite index="8-4,8-5,8-6">A 'black hole star' is an object in which a black hole is surrounded by a large gas cloud. The gas hides the accretion, the fall of matter into the black hole, but the energy from that process causes the cloud to glow from within. The spectrum of such an object may resemble that of a cool red star, such as a red giant.</cite> That's the structural model the team is proposing, and it's a tidy explanation for a nagging observational problem.

<cite index="12-4">Since JWST began science operations in 2022, its deep images of the distant universe have repeatedly turned up compact, extremely red sources that astronomers quickly labeled 'little red dots.' Their brightness, color and number at early cosmic times challenged standard expectations for both young galaxies and ordinary accreting black holes.</cite> What they were has been an open argument in the field.

<cite index="11-4">This object, described in a study published in Nature by researchers at the Institute of Science and Technology Austria and international collaborators, may help explain how billion-solar-mass black holes formed so soon after the Big Bang.</cite> That's the deeper question here. Theorists have long struggled to account for black holes with masses in the billions of solar masses appearing so early in cosmic history. You need something to grow them fast, and a gas-enshrouded accretion phase is one candidate mechanism.

<cite index="8-7,8-8">MoM-BH-1 was discovered as part of the Mirage or Miracle observation program, which focuses on objects that may turn out to be very distant galaxies with a redshift of approximately 10 or greater.</cite> The team wasn't hunting for a new object class. They stumbled into it.

<cite index="10-4,10-5">According to the international team of astronomers, the bright red dot appears to be a combination of a massive black hole and a star, around the size of our entire solar system. The team arrived at that conclusion after modeling a variety of scenarios to explain the object's peculiar characteristics.</cite> Modeling your way through an exhaustive set of alternatives before landing on a new object class is exactly the kind of methodological caution this kind of claim requires, and the fact that they did it matters.

<cite index="12-2,12-3">The same physical configuration, gas-enshrouded black holes, appears consistent with the larger population of little red dots that JWST has found in the early universe. Open questions remain: how common these objects were, how long the gas cocoon phase lasts, and whether they represent a rapid pathway to the first supermassive black holes.</cite>

A few things to keep in mind before this gets overstated in the popular press. This is one object. <cite index="15-15,15-16">As Naidu put it, 'These little red dots seem to be everywhere in the early universe but essentially disappear by the present day. What exactly these objects are has been one of the most debated topics of the JWST era.'</cite> One confirmed example doesn't settle that debate. It focuses it.

<cite index="12-9">Preprint versions of the analysis circulated earlier on arXiv</cite>, so the result has had community scrutiny before formal publication. That's a healthy sign. But the model still needs to survive independent replication against other little red dot candidates. The paper, cited by ScienceDaily as published in Nature on August 12, 2026, is the place to start if you want to evaluate the spectral fitting yourself. Read the methods before the abstract.
