Author's Note: Why are the auroras seasonal?
One of the coolest things about studying science in space is that for every answer you find, you'll come upon another question. The study of auroras is a super cool example of that; sure, they know a couple things about why they're seasonal. But that's only a really small part that doesn't explain the whole. To get more information about auroras in general, NASA launched the THEMIS mission, and you can read about the agency's findings here.
