Astronomers using the James Webb Space Telescope have discovered a bright red object that may be a previously unknown class of "black hole star" [1, 2].
The discovery challenges current understandings of how the first celestial objects formed. Because the object's luminosity exceeds the limits of normal stellar processes, it suggests a new mechanism for energy production in the early universe [3, 4].
Researchers from MIT and other institutions identified the object in deep-space observations [1, 2]. While it appears star-like, the object emits approximately 100 billion times more energy than any known star [3, 4]. This extreme energy output indicates that the object is not a traditional star, but rather a massive black hole surrounded by a dense cloud of gas [1, 2, 4].
The object dates back to a period roughly 660 million years after the Big Bang [5]. Its physical scale is immense, with a size comparable to the Solar System [2]. Data suggests the central black hole possesses a mass totaling tens of thousands of solar masses [6].
This object is part of a broader study of "mystery red dots" captured in early-universe images [3]. The luminosity of these objects is too high to be explained by the fusion of hydrogen and helium, the process that powers stars like the Sun [4]. Instead, the energy is generated as the central black hole feeds on the surrounding gas cloud [2, 4].
Astronomers believe these findings provide a glimpse into the "cosmic dawn," the era when the first stars and galaxies began to illuminate the darkness of space [4]. By studying these objects, researchers hope to understand how supermassive black holes grew so quickly in the infancy of the universe [1, 2].
“The object emits approximately 100 billion times more energy than any known star.”
The identification of a black hole star suggests that the early universe contained hybrid objects that bridge the gap between the first stars and the first supermassive black holes. If these objects are common, it provides a missing link in cosmic evolution, explaining how black holes reached massive proportions much faster than current theoretical models predict.
