Gamma Ray Bursts - The Most Powerful Objects in the Universe?

Satellites in the 1960's looked for a type of light called Gamma Rays. They found bursts of Gamma Rays coming from outer space! They can't hurt you. They are stopped by the Earth's atmosphere.

We have now seen many more Gamma Ray Bursts. They happen once a day. They come from all over the sky. They come from the birth of black holes in other galaxies.

Some bursts are short. They come from two neutron stars joining. Other bursts last longer. They come from exploding stars, called supernovae.
