Astronomers discover new celestial object, dubbed a "black hole star," using James Webb Space Telescope data
Key points
- Hundreds of red dots, believed to be baby quasars, were found in James Webb Space Telescope data.
- One object was extremely red and bright, not fitting known astrophysical classifications.
- Astronomers concluded it is a "black hole star," producing black hole-level energy.
- The object exhibits a deep "Balmer break" and contains only hydrogen and helium.
Discovery of a Unique Celestial Object
In 2024, astronomers examining datasets from the James Webb Space Telescope observed numerous small red dots, initially thought to be nascent quasars, dating back to when the Universe was only a few hundred million years old. Among these, one particular object stood out due to its extreme redness and brightness, which did not align with any previously identified astrophysical object.
Introducing the "Black Hole Star"
Scientists have now classified this unique object as a "black hole star." This designation reflects its stellar size combined with an energy output far exceeding what nuclear fusion could produce in a star, instead matching the energy levels of an active black hole. This finding was detailed in a paper published in the journal Nature.
Unusual Spectral Characteristics
Initially, researchers hypothesized that the object's intense red color was due to surrounding dust. However, further analysis revealed that while the light produced was exceptionally bright, it completely vanished below certain wavelengths, a phenomenon known as a "Balmer break." This observed Balmer break was the deepest ever recorded, and the object's spectrum showed no evidence of metals or elements other than hydrogen and helium, indicating a primitive composition.
Implications for Astrophysics
The identification of this "black hole star" presents a new category of celestial bodies that do not fit into current astrophysical models. Its unique energy production and spectral properties offer new avenues for understanding the early universe and the formation of extreme cosmic objects.

Astronomers analyzing James Webb Space Telescope data identified a new celestial object, named a "black hole star," which is star-sized but emits energy comparable to an active black hole. This discovery challenges existing astrophysical classifications and provides new insights into early universe objects.
