A solar storm producing spectacular colored lights may be approaching parts of the Midwest on Friday. The storm – also known as a Aurora Borealis or Northern lights - may be seen in parts of the Great Lakes region and Northeast. Northern lights are caused when gaseous particles in the Earth's atmosphere collide with charged particles released from the sun's atmosphere. When these particles collide, they produce amazing colors in the sky that can be seen from miles away.
Check out these photos of northern lights captured from around around the world.
