A multihued aurora ripples across the night sky over Tromsø, Norway, on January 19. Auroras happen when high-energy particles from the sun slam into Earth's atmosphere, exciting gas molecules in the air and causing them to emit light. The colors seen depend on the type of molecules involved and the altitude at which the most interactions are happening. Green is the most common shade for auroras and is produced by oxygen molecules at relatively low altitudes—between 62 and 186 miles.
