Gamma rays are high-energy photons produced by some of the most violent events in the universe. We explore this powerful radiation in more detail here.

The gamma-ray burst GRB 221009A trumped such previous explosions. Most instruments designed to detect this type of light couldn't handle the anomalously extreme radiation.

Scientists traced a high-energy blast of radiation - called a gamma-ray burst - to the merger of two neutron stars and an explosion called a kilanova that resulted from the cosmic collision.
