So many beautiful aurora photos going around right now. Wonder where those amazing colors come from? Here's a helpful breakdown.

When you split up the light of a typical aurora, it looks like this.

Many colors from just nitrogen & oxygen!

@coreyspowell I'm a physicist and I didn't understand anything about this explanation. Why is the magnetic field asymmetric? Why does the color depend on the concentration, if it's due to electrons falling back to their ground state (it is, isn't it)? Why would charged particles excite atomic oxygen differently if the concentration is higher?

Idk, nice fonts and everything, but this infographic didn't do much for me.

@lakens Mijn echtgenote, Peruaanse, lachte véél te hard om deze grap.
