Explanation:

The Aurora is an incredible light show caused by collisions between electrically charged
particles released from the sun that enter the earth's atmosphere and collide with gases
such as oxygen and nitrogen. The lights are seen around the magnetic poles of the northern
and southern hemispheres.
Bottom line: When charged particles from the sun strike atoms in Earth's atmosphere, they
cause electrons in the atoms to move to a higher-energy state. When the electrons drop
back to a lower energy state, they release a photon: light. This process creates the beautiful
aurora.
