US EditionScientists spot the brightest flare yet from a supermassive black hole
- On Nov 4, 2025, researchers announced the brightest supermassive black hole flare, shining with the light of 10 trillion suns and first spotted in 2018 by the Zwicky Transient Facility at Palomar Observatory.
- Analysis points to a tidal disruption event in which the ill-fated star was shredded by Active Galactic Nucleus J2245+3743.
- The observations show it brightened by a factor of 40 over a few months, peaked at 30 times previous luminosity, and has been decaying for years since.
- Scientists say the event will remain observable for a few years, and researchers expect ground-based telescopes to aid study while teams conduct ZTF archival searches and await Vera C. Rubin Observatory data.
- From about 10 billion light-years away, cosmological time dilation stretches light and time, making long-term surveys like ZTF crucial to spotting distant phenomena in the young universe.

Miami (USA), Nov 4 (EFE).- A group of astronomers in the United States detected a flash equivalent to the light of 10 billion suns around a massive black hole located about 10 billion light years from Earth, the largest flare ever recorded around one of these cosmic bodies. The finding can help scientists better understand the environment surrounding supermassive black holes, about which they still do not fully understand how they are formed. Re…
A massive star devoured by a black hole produces a luminosity equivalent to 10,000 billion suns.
Star-eating black hole unleashes record-setting energetic flare | Honolulu Star-Advertiser
WASHINGTON >> Scientists are observing the most energetic flare ever seen emanating from a supermassive black hole, apparently caused when this celestial beast shredded and swallowed a huge star that strayed too close.
