James Webb Space Telescope's strange little red dots may really be 'black hole stars', X-ray data suggests

Key Points:

• The discovery of an X-ray signal matching the location of a "little red dot" observed by the James Webb Space Telescope (JWST) supports the theory that these dots are "black hole stars," dense gas clumps energized by growing supermassive black holes.
• These little red dots, extremely distant and cool compared to most stars, may represent a crucial missing link in understanding the formation of supermassive black holes and the galaxies that develop around them, addressing a longstanding astronomical mystery.
• The X-ray source, identified in archival data from NASA's Chandra X-ray Observatory, suggests that some little red dots may be transitional objects where black holes are emerging from within gas clouds, allowing X-rays to escape through gaps in the cloud.
• If confirmed, this finding would provide the strongest evidence yet that supermassive black hole growth occurs inside little red dots and could illuminate the early stages of galaxy and black hole formation, a key goal of JWST's mission.
• Alternative explanations, such as the presence of exotic hot dust, are considered unlikely, making the black hole star hypothesis the most plausible interpretation of the observed phenomena.
