Context: Astronomers have discovered a new type of supernova triggered when a massive star interacted with a black hole in a binary system, leading to a rare and powerful stellar explosion about 700 million light-years away.
About New type of supernova detected:
• What It Is?
• A previously unobserved stellar explosion caused by a black hole companion siphoning material from a massive star until it collapses. Occurred in a binary system where both the star and black hole had similar masses (~10 times the Sun).

• Occurred in a binary system where both the star and black hole had similar masses (~10 times the Sun).
• Identified Through:
• Artificial Intelligence algorithms that scanned for unusual cosmic explosions in real time. Follow-up observations by multiple ground-based and space-based telescopes immediately after detection.

• Key Features:
• Binary Interaction – Star distorted and stripped by black hole’s gravity over years before explosion. Extreme Energy Release – Explosion emitted more energy in a second than the Sun will in its entire lifetime. Mass Loss Before Explosion – Hydrogen layer ripped away, exposing helium core. Post-Supernova Feeding – Black hole consumed remaining stellar debris, increasing in mass and power. AI-Enabled Early Observation – Rare opportunity to capture full pre- and post-explosion timeline.
