Gamma Ray Bursts
Gamma Ray Bursts (GRBs) are the most energetic events ever detected.
-
A short burst of gamma rays 5.47 billion light years from Earth caused by the collision of two neutron stars that put out more energy in a half-second than the Sun could in 10 billion years has revealed the truth about luminous infrared kilonova. -
Astronomers investigating gamma ray emissions have discovered that certain active galaxies are giving off bursts in regular patterns. This, the team says, could be an indication of galaxies harboring two supermassive black holes in their centers.

The universe is full of explosions, and now astronomers have described a brand new class of space signals. Named fast blue optical transients (FBOTs), these events are very bright and throw off incredible amounts of energy in a short amount of time.

Gamma-ray bursts are already the most energetic events we know of in the universe. Now, astronomers have detected the most powerful one ever. The competition isn’t even close, either – it's almost a thousand times more powerful than your average GRB.
