From the Sun to the sky — the full process
1. Solar Wind — Charged particles stream from the Sun at 400–800 km/s, carrying the interplanetary magnetic field toward Earth.
2. Magnetosphere — When Bz points southward, Earth's magnetic field opens and funnels solar particles down toward the polar auroral zones.
3. Atmospheric Collision — Solar particles slam into oxygen and nitrogen molecules at 100–300 km altitude, exciting atoms to higher energy states.
4. Light Emission — Excited atoms release energy as visible light. Oxygen at 100 km glows green, at 200 km red; nitrogen produces blue and purple hues.
