This video is part of the “Cosmic Concepts” video series. It illustrates how infrared light is heat radiation and how infrared observations have numerous applications wherever temperature is important, such as in medicine, energy audits, and firefighting. An overview of how infrared observations are used in astronomy is provided as well. Whether one is studying planets, stars, nebulae, galaxies, or the distant universe, infrared astronomy plays an important role.
