Episode Synopsis

Professor Matthew Graham discusses the most powerful black hole flare ever recorded, which shone like 10 trillion suns from an Active Galactic Nucleus (AGN). Material falling into the supermassive black hole forms an accretion disc, releasing intense radiation. This 10-billion-year-old event was detected using computer cameras. Graham explains that these black holes are ancient "seeds" of galaxies, acting as cosmic vacuum cleaners, such as when a large star gets shredded. Guest: Professor Matthew Graham. 1/2
