Gamma radiation

Gamma rays are a type of electromagnetic radiation that has very high energy, 10,000 times more energy than radiation that is visible to the naked eye. Gamma radiation is associated with phenomena involving radioactivity. That is why gamma rays are produced in the cores of nuclear power plants. Gamma-ray astronomy is a science of extreme events produced in the Universe: supernovas, massive amounts of energy being absorbed by a black hole, etc.
