Northern Lights

This past Monday the aurora borealis or northern lights were visible across many areas of the United States.

"According to the Geophysical Institute at the University of Alaska Fairbanks, auroras are created when electrons from space collide with atoms and molecules of gases (like oxygen and nitrogen) from the Earth's atmosphere. These collisions produce the amazing displays of light that we can see."
