Question

How are auroras formed?

Answer 1

In reality they are just Illusion or Dust Particles by refraction of light

Answer 2

The aurora borealis (northern lights) form when charged particles emitted from the sun during a solar flare penetrate the earth's magnetic shield and collide with atoms and molecules in our atmosphere. These collisions result in countless little bursts of light, called photons, which make up the aurora.
