James Webb’s little red dots may be monster stars that seeded black holes
Astronomers have proposed that mysterious 'little red dots' observed by the James Webb Space Telescope are actually massive, ancient stars. These supermassive stars could explain the rapid formation of early black holes and the unique light signatures observed in the early universe.
Why it matters
This discovery challenges existing models of galaxy and black hole formation, providing a potential solution to the mystery of how supermassive black holes appeared so quickly after the Big Bang.
Mysterious, compact objects discovered in the early universe may actually be enormous "monster stars" with masses up to 100,000 times greater than the Sun.According to a new study by the Center for Astrophysics | Harvard & Smithsonian, these giant stars could explain the unusual features of the "little red dots" spotted by the James Webb Space Telescope.Their eventual collapse could also explain how the universe's first supermassive black holes formed so quickly, less than a billion years after the Big Bang.The study, led by Devesh Nandal of the Harvard College Observatory, part of the Center for Astrophysics in Cambridge, Massachusetts, presents a single model that matches the objects' light spectrum, compact appearance, and chemical makeup."To my knowledge, it is the first model that can explain so many of the observed properties at once, from the spectra to the morphology to the chemical signatures," Nandal said in a statement released by…
