Atmospheric Layers: The Occurrence of Aurora Phenomenon

Auroras, also known as northern and southern lights, are colorful displays in the night sky near the poles. They occur when solar winds, composed of charged particles, enter Earth's magnetic field and collide with atmospheric gases. These collisions excite the gases, which emit light as they return to their normal state. Different gases produce different colors, such as blue from nitrogen and red or green from oxygen. During solar storms, the intensity of solar winds increases, leading to more spectacular auroral displays.
