What are Autora Borealis caused by?

Aurora Borealis, or the Northern Lights, are caused by the interaction between charged particles from the solar wind and the Earth's magnetic field and atmosphere. When these solar particles collide with gases like oxygen and nitrogen in the Earth's upper atmosphere, they excite the atoms, causing them to emit light. This phenomenon typically occurs near the polar regions, where the magnetic field lines converge, resulting in vibrant displays of green, pink, and red lights. The intensity and color of the auroras depend on the type of gas involved and the altitude at which the collisions occur.
