Everyone knows the northern lights. Well, I wonder if there is anyone who is not a fan. I am very fascinated by the Northern lights. It even has a cooler name: aurora. So, do you know how the Northern Lights form?

The Earth is constantly bombarded by the solar wind. Charged particles from the Sun collide with oxygen and nitrogen atoms in the Earth's atmosphere in the ionosphere. This turns into the glowing colors known as the Northern lights.

I never knew it was formed by wind bombardment. Did you know?
