What's Happening?
Astronomers have observed what may be the first known case of a massive star exploding while interacting with a black hole, named SN 2023zkd. This event was first spotted by the Zwicky Transient Facility and flagged by an AI system designed to identify unusual cosmic events in real time. The early alert allowed telescopes worldwide to capture the event from its earliest stages. SN 2023zkd exhibited a long-lived pre-explosion phase and a double-peaked light curve, suggesting the star was under intense gravitational stress, likely due to a nearby black hole.

Why It's Important?
The discovery of SN 2023zkd highlights the role of AI in spotting rare cosmic events, enabling detailed study and advancing our understanding of stellar explosions. The findings suggest a new class of stellar explosions, providing insights into the complex lives of massive stars in binary systems. The use of AI in astronomy is proving crucial for identifying and studying rare events, paving the way for future discoveries. The research underscores the importance of AI in revolutionizing the field of astronomy, enabling scientists to connect the dots between how a star lives and how it dies.
What's Next?
The findings point to the role upcoming facilities like the Vera C. Rubin Observatory will play in documenting the entire southern sky every few nights. Combined with real-time AI detection, these observations will enable astronomers to identify and study more of these rare, complex events. The discovery of SN 2023zkd provides a blueprint for an entirely new class of stellar death, promising more discoveries to come. The research is described in a paper published in the Astrophysical Journal.
