The Secrets of Aurora Borealis: 7 Surprising Facts You Never Knew

1. Aurora Borealis is not unique to Earth, it can also be observed on other planets in our solar system, including Jupiter, Saturn, and Mars.

2. The scientific term for Aurora Borealis is "aurora polaris" or "northern lights" because it can only be observed in the northern hemisphere.

3. Aurora Borealis occurs when charged particles from the sun, also known as solar wind, interact with Earth's magnetosphere.

4. The most common color of Aurora Borealis is green, which is caused by collisions with oxygen atoms at an altitude of about 60 miles.
