Record-Setting Black Hole Flash Dazzles Astronomers: “One-In-A-Million” Flare Blasts Light = 10 Trillion Suns
Astronomers observed the brightest black hole flare ever recorded, outshining 10 trillion Suns. The event, caused by a supermassive black hole shredding a giant star, occurred in a galaxy about 10–11 billion light-years away. Detected in 2018 by Caltech’s Zwicky Transient Facility, the flare peaked over months and is now fading. Findings led by Matthew Graham were published Nov. 4, 2025, in Nature Astronomy.
