American astronomers have discovered the most powerful cosmic explosion ever recorded, a supermassive black hole flare that unleashes the energy equivalent of converting our entire Sun into pure energy—showcasing the incredible forces at work in our universe.
Story Highlights
- Astronomers detected a black hole flare 30 times brighter than any previously observed, equivalent to 10 trillion suns.
- The flare originated 10 billion light-years away from supermassive black hole J2245+3743, making it the most distant such event recorded.
- NASA and NSF-funded facilities, including Caltech’s Zwicky Transient Facility, made the groundbreaking discovery.
- The event resulted from a massive star being torn apart by the black hole’s gravitational forces in a tidal disruption event.
Record-Breaking Discovery Illuminates Deep Space
Scientists using advanced American astronomical facilities have identified the brightest and most distant supermassive black hole flare ever recorded.
The flare from active galactic nucleus J2245+3743 reached peak luminosity equivalent to 10 trillion suns, surpassing previous records by a factor of 30. This extraordinary event occurred when the universe was approximately 4 billion years old, providing unprecedented insights into cosmic phenomena from the early universe.
The discovery emerged from collaborative efforts between multiple American institutions, including Caltech’s Palomar Observatory and the W. M. Keck Observatory. Professor K. E. Saavik Ford from CUNY Graduate Center emphasized the event’s significance, stating that converting our entire Sun to energy using Einstein’s E=mc² formula equals the energy this flare has continuously produced since observation began.

Advanced American Technology Enables Breakthrough
The Zwicky Transient Facility at Caltech’s Palomar Observatory first detected the flare in 2018, with the Catalina Real-Time Transient Survey providing additional confirmation.
Over five years, researchers watched the flare brighten by a factor of 40, reaching its extraordinary peak luminosity. Follow-up spectroscopic observations with the W. M. Keck Observatory confirmed the phenomenon’s extreme brightness and ruled out alternative explanations.
NASA’s Wide-field Infrared Survey Explorer mission provided crucial data that helped scientists confirm the flare’s true brightness. Ford noted that initial concerns about directional beaming were eliminated through WISE data analysis, establishing that the object genuinely glowed with unprecedented luminosity in all directions rather than focusing light specifically toward Earth.
Stellar Destruction Powers Cosmic Fireworks
Scientists determined that the flare resulted from a tidal disruption event, in which a massive star ventured too close to the 500-million-solar-mass black hole and was torn apart by gravitational forces.0
This catastrophic stellar destruction created the brilliant explosion that astronomers observed across billions of light-years. The event provides researchers with valuable data on the behavior of supermassive black holes and the extreme physics governing these cosmic giants.
