Webb reveals a massive black hole dwarfing its tiny host in the early universe
JWST directly measured a ~50 million-solar-mass black hole in the little red dot QSO1, seen when the universe was about 700 million years old, and found it vastly outweighs its host galaxy (host mass < ~20 million solar masses), making it a “naked” black hole. The object is magnified and stretched by gravitational lensing from Abell 2744 (roughly 6x magnification, 3.5x stretch), enabling spectroastrometry with JWST’s NIRSpec to map gas motion and pin down the mass. The result reinforces that local-universe black-hole mass methods can apply to early-universe objects and suggests such seeds could form before their galaxies, though two exotic origin scenarios—direct collapse or primordial black holes—remain on the table.
