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.

The record-setting cosmic outburst was actually a gamma-ray burst, the most powerful class of cosmic explosions.

"The sheer amount of radiated energy from these bursts is so large that you can't power them with a core collapse stellar ...
