People are a little facetious when describing the Northern Lights. They dance and stuff, you know. The lights, I mean, not the people, although they may do that, too. It’s a little boring to be honest.
It goes to show, too: Human stories aren’t half as badass as nature’s.
Honestly. Auroræ happen because the Sun’s energy, in the form of particles, hits Earth, gets focused in on the polar regions by a magnetic field, and “collides” with particles in the Earth’s atmosphere.
Sun’s energy. Earth’s magnetic field and atmosphere.
Take one of them away, and there is no life on this planet. “Dancing” aurora, indeed…
