What are northern lights?

Answer 2

The earth is a big magnet...
The Northern Lights are auroras or luminous curtains of light that often can be seen in the dark skies near the North and South poles. They occur when a space weather event energizes the magnetic force field shielding our planet, churning up electrons and protons and causing them to smash into the mix of gases in the upper atmosphere. The result is a bright glow that can last anywhere from a few seconds to a few hours.
