JWST spots 'little red dots' that defy simple black hole explanation

Astronomers using the James Webb Space Telescope had largely concluded that mysterious compact objects called 'little red dots' were supermassive black holes obscured by dust. But two newly analyzed dots studied by teams led by de Graaff and Naidu show a distinctive Balmer break—a spectral signature usually associated with hot stellar surfaces—that standard black hole models don't produce, complicating the picture.
