‘The hell are they?
So what the hell are these amazing dream-like light shows floating above our heads? The glow comes from the collisions of fast moving electrons with oxygen and nitrogen molecules in the magnetosphere. The magnetosphere is the portion of the atmosphere that is directly controlled and influenced by the magnetic field of the earth. When these collisions happen, the electrons transfer some of their energy into these two molecules, exciting them. These hyped up molecules return to their normal state by releasing photons. In large enough numbers, the collisions of photons produce light visible to the naked eye.
This sh*t happens when science explodes above your head. Shut up and watch.
