US EditionWhy This Supernova Was Unusual for Several Reasons
Artificial intelligence detected a rare double supernova caused by a massive star’s interaction with a black hole, revealing new insights into stellar deaths and black hole behavior.
- Astronomers discovered an unusual supernova named SN 2023zkd in July 2023 about 730 million light-years away, detected by the Zwicky Transient Facility using AI.
- The star had been brightening for roughly 1,500 days before exploding due to intense gravitational stress from orbiting a black hole companion.
- The supernova exhibited rare behaviors, including multi-year brightening and re-brightening 240 days after discovery, defying typical supernova light curves.
- Lead author Alexander Gagliano noted that this discovery provides the clearest proof so far that interactions between a star and a nearby black hole can trigger the star’s explosion, emphasizing the important role of AI in identifying such events.
- This finding suggests new classes of stellar explosions and demonstrates AI's power to catch rare cosmic events in real time for detailed study.

Star's Fatal Dance: Black Hole Tango Ends in Explosive Supernova | Science-Environment
Star's Fatal Dance: Black Hole Tango Ends in Explosive Supernova A catastrophic cosmic event resulted in a new type of supernova, observed by astronomers as a massive star tried to consume a black hole in a destructive gravitational dance. The star, around 10 times the mass of our sun, exploded after being distorted by the black hole’s pull.The seminal event, situated 700 million light-years away from Earth, was witnessed in real-time thanks to …
Never-before-seen kind of supernova spotted after using AI to scan the skies
With help from AI, astronomers have spotted a never-before-seen kind of supernova that seems to have been blowing up just as it was trying to gobble down a black hole. Scientists may have spotted a never-before-seen kind of supernova, after using a Spotify-like artificial intelligence (AI) to scan the skies for strange activity. The AI unearthed signs of what could have been a huge star blowing up just as it was attempting to gulp down a nearby …
Spotify-like AI helps discover never-before-seen supernova as greedy star attempts to eat a black hole
With help from AI, astronomers have spotted a never-before-seen kind of supernova that seems to have been blowing up just as it was trying to gobble down a black hole.
New type of supernova detected as black hole causes star to explode
WASHINGTON :Astronomers have observed the calamitous result of a star that picked the wrong dance partner. They have documented what appears to be a new type of supernova, as stellar explosions are known, that occurred when a massive star tried to swallow a black hole with which it had engaged in a lengthy pas de de
AI Has Spotted a 'Very Strange' Stellar Death Unlike Anything Astronomers Have Ever Seen
(Image Credit: Melissa Weiss/CfA) Welcome to this installment of The Intelligence Brief… This week, astronomers have documented an unprecedented stellar death in which a massive star was torn apart by a black hole even as it exploded as a supernova, producing a cosmic event unlike anything seen before. In our analysis, we’ll explore 1) how the event, designated SN 2023zkd, was detected in real time by an AI algorithm scanning the skies for unusu…
