The Black Hole That Acts Like a Star: How Webb Found a Bizarre New Cosmic Object at the Dawn of Time

The James Webb Space Telescope has a habit of finding things that were not supposed to exist. Its latest surprise, described in the journal Nature in August 2026, is a genuinely new kind of cosmic object that astronomers have nicknamed a 'black hole star'. Formally catalogued as MoM-BH*-1, it is a strange hybrid that behaves like a colossal star on the outside while hiding something far more violent within.

A star that isn't really a star

What makes the object so unusual is the mismatch between how it looks and what powers it. Its light carries the spectral fingerprints you would expect from an enormous star, yet no star could physically produce that much energy. Researchers describe an output around 100 billion times greater than a typical star, generated not by nuclear fusion but by a black hole voraciously feeding on the gas around it.

A window into the cosmic dawn

The object is seen as it was roughly 660 million years after the Big Bang, a period astronomers call the cosmic dawn. That timing is what makes it so valuable, because it may help answer one of the field's hardest questions: how did black holes billions of times heavier than the Sun manage to grow so quickly in the universe's first few hundred million years? Some scientists have called it the first supermassive black hole 'teenager' ever seen.

Solving the mystery of the Little Red Dots

The discovery also speaks to another puzzle Webb has raised. Since it began surveying the deep sky, the telescope has spotted hundreds of tiny, compact 'Little Red Dots' scattered through the early universe, and nobody has been quite sure what they are. The new work suggests that at least some of these enigmatic dots could themselves be black hole stars, cloaked in dense envelopes of hydrogen that give them their reddish glow.

Caution before celebration

As striking as the finding is, astronomers are being careful. Defining an entirely new class of object from a single example is risky, and headlines have framed the result as a question of 'mirage or miracle'. Confirming that MoM-BH*-1 truly represents a distinct population, rather than an unusual one-off, will require more Webb observations and independent analysis before the label sticks for good.

Even with that caution, the potential payoff is large. If black hole stars are real and common, they could reshape how we think black holes and galaxies grew together in the early universe. For stargazers watching from the southern skies of Australia and elsewhere, it is a reminder that the cosmos still has categories we have not even named yet, waiting in the faint red light of the first billion years.
