Cosmic trio of supermassive black holes spotted in a distant galaxy
TL;DR Summary
Using JWST/NIRSpec, astronomers found three active supermassive black holes in the distant galaxy J0148-4214—a central 80‑million-solar-mass hole, a 600,000-solar-mass companion, and a ~2‑million-solar-mass third hole—suggesting rapid early‑universe black‑hole growth via mergers; the third hole’s fate is uncertain, but such systems could emit long‑wavelength gravitational waves detectable by future space‑based observatories like LISA.
