How does the energy released by a Gamma-Ray Burst (GRB) in seconds compare to the Sun's total lifespan energy output?

Answer

It releases as much energy as the Sun will release over its entire 10-billion-year lifespan, compressed into the gamma-ray spectrum

The comparison emphasizes the extreme, focused power of a Gamma-Ray Burst. In just a few seconds of its emission phase, a typical GRB releases an amount of energy equivalent to the total energy output that our Sun is projected to generate over its entire 10-billion-year existence. Crucially, this vast amount of energy is concentrated within the high-energy gamma-ray spectrum. This immense concentration explains why even a tiny fraction of that energy, after traveling light-years across space, retains enough power to significantly alter planetary atmospheres upon arrival.
