Auroras are natural light displays in the sky that occur in high latitude regions due to the interaction between charged particles from the solar wind and Earth's magnetic field. The two main types of auroras are the Aurora Borealis in the Northern Hemisphere and the Aurora Australis in the Southern Hemisphere. Rare types such as STEVE and Proton Auroras can also be observed, with scientific measurement and observation techniques including ground-based observatories, satellites, and historical observations dating back to ancient civilizations.
