Story summary

The James Webb Space Telescope (JWST) revealed mysterious 'Little Red Dots' (LRDs) in the early universe, initially thought to be baby black holes.
A study proposes these LRDs are globular clusters in formation, with light from young stars and a V-shaped spectrum linked to a supermassive star.
Researchers estimate LRD density matches local globular clusters, implying they illuminate the universe's early structure formation and motivate future observations of chemical signatures.
