Story summary

Astrophysicists Marco Ajello and Jonathan Zrake have made a groundbreaking discovery about the active galactic nucleus PG 1553+153, proposing it contains a binary supermassive black hole system. Their analysis of 120 years of data revealed a striking 20-year light variation pattern, hinting at two black holes with a 2.5:1 mass ratio. Advanced gravitational wave detection may soon confirm this cosmic revelation.
