The Little Red Dots That Confused Astronomers



The James Webb Space Telescope found hundreds of tiny red dots in the early universe — and for a while, neither of the two possible explanations could be true. If they were galaxies, they held too many stars, too early. If they were black holes, they were too heavy, too quiet in X-rays, and missing their dust glow. Then astronomers proposed something stranger: a black hole star — a young black hole drowning in its own food supply. And in January 2026, a correction in Nature shrank the monsters a hundred-fold. This is the evidence, step by step: what we know, what is still argued about, and why the dots did not break the universe — they revealed a phase of growing up we had never seen.

Question for you: black hole in a cocoon, monster star, or something nobody has thought of yet — which explanation do you bet on?
