Auroras happen when the sun sneezes. Not literally, but close—it blasts charged particles our way.
Those particles crash into Earth’s magnetic field, and poof, you get neon curtains in the sky. It’s basically a giant, celestial lava lamp.
Quirky fact: the colors depend on which gas gets hit. Oxygen makes green and red—like a traffic light for aliens. Nitrogen gives blue and purple—emo sky vibes.
