Gamma Ray Burst Detected

Gamma Ray Burst Detected:

A gamma-ray burst that recently hit our solar system was so bright, it temporarily blinded gamma-ray instruments in space, according to a NASA release.

  • Gamma Ray Burst (GRB) are short-lived bursts of gamma-ray light, the most energetic form of light.
  • GRB emits more energy in a few seconds than our Sun will emit in its lifetime and has two distinct emission phases:
  • The short-lived prompt emission (the initial burst phase that emits gamma-rays), followed by a long-lived multi-wavelength afterglow phase.
  • The shortest GRBs likely mark the collision of two compact stellar remnants called neutron stars, and the longest bursts are thought to arise when a massive, rapidly spinning star collapses to form a black hole.
  • When a GRB erupts, it is briefly the brightest source of cosmic gamma-ray photons in the observable Universe.

Gamma Rays:

  • Gamma rays have the smallest wavelengths and the most energy of any wave in the electromagnetic spectrum.
  • They are produced by the hottest and most energetic objects in the universe, such as neutron stars and pulsars, supernova explosions, and regions around black holes.
