James Webb Telescope finds mysterious "little red dots," possibly early galaxies or black holes.

The James Webb Space Telescope has discovered mysterious "little red dots" in the early universe, which appear as small, reddish objects with unusual light signatures. These transient features, observed when the universe was less than a billion years old, may represent the initial stages of galaxy and black hole formation. Researchers suggest they could be actively accreting supermassive black holes, though debate continues on their true nature.
