Story summary

New spectral analysis with the James Webb Space Telescope suggests little red dots (LRDs) may be cool red stars concealing black holes, after being initially identified as ancient galaxies.
The Cliff, a notable LRD, is located 11.9 billion light-years away and shows an unusually thick atmosphere.
The study indicates these objects could represent the early stages of supermassive black holes found in most galaxies, challenging existing theories of galaxy formation.
