The Atmosphere: the Magnetosphere

The video explains the phenomenon of the northern lights, also known as aurora borealis. It describes how the Earth's magnetosphere interacts with solar wind, trapping ions that lead to the formation of auroras. The Van Allen radiation belt and the ionosphere play crucial roles in this process, resulting in the spectacular light displays seen in the sky.
