How does Aurora happens?

Auroras occur when charged particles from the solar wind collide with gases in Earth’s atmosphere, primarily oxygen and nitrogen. These interactions excite the gas molecules, causing them to emit light as they return to their normal state. The resulting display of colors, typically seen near the polar regions, is known as the aurora borealis in the Northern Hemisphere and aurora australis in the Southern Hemisphere. The phenomenon is more intense during periods of heightened solar activity.
