AI-Powered Discovery of a Unique Supernova
In a groundbreaking astronomical discovery, researchers have observed what appears to be a new type of supernova, designated SN 2023zkd, approximately 730 million light-years from Earth. This unprecedented event was detected in July 2023 by the Zwicky Transient Facility in California, utilizing an innovative artificial intelligence (AI) system designed to identify unusual cosmic events in real-time

Proposed Scenarios for the Supernova
Scientists have proposed two main scenarios to explain this unique event:
- The massive star, distorted by the black hole's gravitational pull, attempted to engulf its companion, leading to its own explosion due to gravitational stress

5
. - The black hole may have torn the star apart before it could naturally explode, with the resulting debris collision triggering the supernova-like emission
