Question

what is gamma rays burst​

Answer 1

Answer:

Gamma-Ray Bursts (GRBs) are bursts of highly energetic gamma rays lasting from less than a second to several minutes – the blink of an eye on cosmological timescales. They are known to occur at huge distances from Earth, towards the limits of the observable Universe.

Explanation:

When two neutron stars collide, they send out short gamma-ray bursts as they form a black hole. Supernovas, or star explosions, produce longer gamma-ray bursts as the dying stars collapse into black holes.

Answer 2

Answer:

Gamma-ray bursts are the strongest and brightest explosions in the universe, thought to be generated during the formation of black holes. ... Though they last mere seconds, gamma-ray bursts produce as much energy as the sun will emit during its entire 10-billion-year existence.
