The Universe’s mystery is unfolding: a new type of “black-hole star” discovered by JWST

17 August 2026 Introduction NASA’s James Webb Space Telescope (James Webb Space Telescope – JWST), which studies the early era of the universe, has once again revealed a rare discovery. An MIT-led team of astronomers has detected an unusual luminous point from within a few billion years after the Big Bang. This object, named “MoM-BH*-1,” is thought to be a new type of astrophysical object that combines a star and a black hole. The discovery has been published in the world-renowned scientific journal “Nature.” What was discovered? While analyzing JWST images, astronomers closely examined one of the red luminous sources known as “Little Red Dots.” Typically, astronomers assume such redness is caused by cosmic dust. However, this object’s light profile did not match dust-related effects. In particular, a sudden drop in light within a specific wavelength range known as the “Balmer Break” was far deeper than what is seen in ordinary stars. This object shone with a brightness 100 billion times greater than that of a normal star. Since this amount of energy cannot be produced through nuclear fusion, the research team had to look for another cause. Black-hole star: explanation When astronomers added an active black hole to their computer modeling, they obtained results consistent with JWST measurements. According to this, at the center of the object is a black hole with a mass about one hundred thousand times that of the Sun. Surrounding this black hole is a dense hydrogen-gas “cocoon” comparable in size to our Solar System. This hydrogen cocoon makes the object appear like a gigantic star. But its true energy source is the energy produced as the black hole accretes the surrounding gas. Because of this distinctive combination, the research team has called it a “Black Hole Star”—a new kind of astrophysical object that has never before been confirmed in the scientific world. A solution to the “Little Red Dots” mystery? Over the past few years, JWST has found numerous puzzling objects called “Little Red Dots” in the early universe. What they are has long remained a mystery to astronomers. This new “black-hole star” discovery offers a possible explanation for that mystery—astronomers believe many of these “red dots” could be similar black-hole–star hybrids. Scientific significance This discovery could significantly affect our understanding of early cosmic evolution. How the “supermassive black holes” (Supermassive Black Holes) seen in the universe today formed is a major unanswered question in astronomy. Researchers suggest these “black-hole stars” may represent an important intermediate stage in explaining how such massive black holes formed and grew within a few billion years after the Big Bang. MIT professor Rohan Naidu, who led the discovery, stated: “An object like this looks like a star, but is 100 billion times brighter.” Since this is not possible through nuclear fusion, he explained, there must be a black hole behind it. JWST’s continuing contribution Launched in 2021, the James Webb Space Telescope has provided unprecedented precision in probing the early universe. Using infrared optics, it can clearly detect astrophysical objects from billions of years ago. This “black-hole star” discovery stands as another major milestone in JWST’s scientific contributions. Future research Researchers note that this discovery is still in its early stages. By finding more such objects and comparing and analyzing their properties, it is believed a complete understanding can be achieved regarding “Little Red Dots” and the origins of early black holes. This research is expected to further expand our scientific knowledge about the origin and evolution of the universe. Conclusion This new discovery of a “black-hole star” once again reminds us how mysterious and wondrous the universe is. This rare hybrid of a star and a black hole has pushed the boundaries of space science further, opening new ways for us to understand the secrets of the universe’s earliest epochs.
