The different colours of the Aurora are created by particles colliding with different gasses in our atmosphere. As the earth has two magnetic poles, we see the Aurora Borealis at the North Pole and you will find the Aurora Australis at the South Pole.
Aurora Borealis means “northern dawn” in Latin. In ancient Roman times, Aurora was the goddess of dawn while Borealis meant northerly, hence the term Aurora Borealis. Most commonly, they are called the Northern Lights. Other variations include polar lights, northern polar lights, aurora polaris, and polar spirits.
