2. Gamma-Ray Burst

Gamma-ray bursts (GRBs) are the universe’s most powerful explosions, releasing more energy in seconds than our Sun will in its entire lifetime. If a GRB occurred close to Earth, its intense radiation could obliterate our ozone layer, leaving the planet exposed to deadly solar and cosmic rays. Astronomers have witnessed bursts like GRB 130427A, serving as stark reminders of this remote but catastrophic threat.
