Q: What is the aurora borealis?

The Answer

Last update 2021.11.23

The aurora borealis, or northern lights, is a dynamic display of bright natural light in Earth's sky, often seen at high latitudes (around the North Pole and the South Pole).

The aurora borealis occur as a result of disturbances in the Earth's magnetosphere caused by the solar wind loaded with charged particles, as they travel at high speed through space to reach the Earth's protective magnetosphere, and interact with the gases of the upper atmosphere, ionizing the gas atoms to emit light of varying colors and shapes.
