What are the mysterious ‘little red dots’ in images of space?
Summary
Astrophysicist Dr. Rohan Naidoo discusses "little red dots" discovered by the James Webb Space Telescope, proposing they are "black hole stars." These objects appear to be infant supermassive black holes shrouded in dense gas, offering clues to how such giants form. While the theory suggests every early galaxy may host one, the astronomical community continues to debate whether these are newborns or already mature black holes.
