The Sun in Infrared Light
The sun is the most familiar source of infrared heat. Much of the warmth you feel on a sunny day comes from infrared radiation rather than visible light.
Seeing the sun in infrared
Astronomers observe the sun with special telescopes and cameras that detect infrared. These images show features of the sun's atmosphere that are not visible in ordinary light, and they help scientists study solar activity.
Why sunshine feels warm on a cold day
Infrared energy from the sun passes through the air and warms whatever absorbs it: your skin, your coat, a brick wall or a dark car roof. That is why a sunny spot feels comfortable even when the air is cold, and why the same spot feels much colder when a cloud passes over.
The same idea in a heater
An infrared heater works on the same principle on a much smaller scale. A hot element gives off infrared energy, a reflector directs it, and people and surfaces in front of the heater absorb it as warmth.
