Why is aurora so different?
The aurora is most often a pale green, but sometimes it includes purple, pink and even red. The color is determined by which molecules or atoms are getting excited, and where. This is because different atoms give off specific colors, in the exact way that neon lights work.
How do these auroras differ?
The unique colors of light produced by a gas are called its “spectrum”. The auroral lights’ colors are determined by the spectra of gases in the Earth’s atmosphere, and the height at which the most collisions take place. Incoming particles tend to collide with different gases at different heights.
