What is Infrared?

Infrared is a form of light... light that we can not see with our eyes, but that we can sometimes feel on our skin as heat.

Watch this short video to get a handle on this gift from the universe.

Infrared light is all around us even though we cannot see it. Find out how this invisible radiation impacts our everyday lives. Everything Scientists Could L...
