Dark lightning sounds like something on a metal album. However, it is a real phenomenon that occurs in nature. It’s existence further adds complexity to the process of lightning generation, which itself, it a complicated process that is being researched today, discoveries still being made.
In 2013, NASA published a video describing the effect. Essentially, lightning produces radiation that the human eye can’t see such as gamma rays and even anti-matter hence the name dark. It is insane to think that this is happening in thunderstorms. This reveals new light on storms as the energies needed to produce dark lightning must be very high.
I thought this was really cool and wanted to share as I love sharing amazing science.
