What is Short gamma-ray burst (sGRB)?

A short gamma-ray burst is like a super-fast flash of light from far away in space, caused by two tiny space rocks crashing into each other.

Imagine you have two toy cars that are really strong and fast. When they hit each other head-on, they make a boom, and that boom sends out a bright flash of light across the room. Now imagine those toy cars are actually super-dense neutron stars, zooming through space at nearly the speed of light. When they crash together, they create a short gamma-ray burst, a quick, powerful flash of energy.

When two neutron stars collide, it's like the biggest toy car crash ever. This crash makes a bright flash that we can see from very far away, even from another galaxy!

This flash is so fast and bright that it’s called a short gamma-ray burst. It only lasts for a few milliseconds, but it can be seen across millions of light-years.

So next time you see a quick flash in the dark, imagine two super strong space rocks having a crash party, that's what makes a short gamma-ray burst!
