Illinois Weather Trivia for October 28th
- On occasion, the Northern Lights are visible in Illinois. It used to be said that these lights were reflections from the polar ice fields, or they were lights from demons' lanterns as they search for lost souls. The Northern Lights are actually caused by high-energy particles from the Sun entering the Earth's atmosphere. These particles collide with air molecules, causing them to vibrate. When the molecules stop vibrating, they sometimes produce visible light. Northern Lights can be colored green, violet, red, or white.
