What is dark lightning?

This is the rainy season. Thunder and lightning are the common things.
What is the colour of lightning as we see in the sky ? It is a white line.

But there is dark lightning too.

Surprised ?


As normal lightning , even the dark lightning is caused due to charged particles within the storm clouds trying to cancel the opposite charges.

As the name suggests , dark lightning is invisible to our eyes as this process do not radiate any heat or light instead it releases bursts of gamma radiation.

Scientists have identified dark lightning preceding the normal flash of ordinary lightning.
