The JWST Might Have Found the First Direct-Collapse Black Hole

Universe Today - Fri, 07/25/2025 - 8:22am

Stellar mass black holes are created by core-collapse supernovae. These occur when massive stars near the end of their lives collapse in on themselves and form a black hole. Supermassive black holes form through mergers with other massive black holes. But their could be a third kind, called direct-collapse black holes, and the JWST found evidence of one.
