Gamma Ray Bursts

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.
