SpaceNew type of supernova, as a black hole triggers a star explosion Posted on August 20, 2025 by Administrator Astronomers said this week they’ve discovered a new type of supernova. It appears to be a massive star that exploded while trying to envelop a black hole companion in its outer layers. If it’s true, it’s one of the strangest stellar explosions we’ve yet seen. The Zwicky Transient Facility discovered the blast, named SN 2023zkd, in July 2023.
