NASA’s James Webb Space Telescope (JWST) has provided the strongest evidence to date for the existence of so-called “black hole stars.” These enigmatic “little red dots,” initially discovered by the JWST in 2022, are compact, very young galaxies hosting actively growing supermassive black holes. Spectroscopic analysis of one such red dot has allowed a team of astronomers led by Vasily Kokorev at the University of Texas at Austin to connect several key pieces of this complex cosmic puzzle.

The finding is significant because these black hole stars represent an early and crucial phase in the co-evolution of galaxies and their central black holes. The JWST’s ability to observe the early universe with unprecedented infrared sensitivity has been instrumental in unraveling the nature of these objects, which formed within the first few hundred million years after the Big Bang. The obtained spectral characterization offers detailed information about the composition, dynamics, and activity of the central black hole, providing a cosmic “barcode” that reveals its intrinsic properties.
