Astronomers report a strange cosmic blast that looked like a kilonova, then behaved like a supernova, hinting at a possible first “superkilonova” and leaving scientists debating how stars truly die.

Astronomers may have discovered the first example of an explosive cosmic event called a "superkilonova," in the form of a gravitational wave signal detected on Aug. 18, 2025.
