Infrared radiation may be used to detect temperature variations.  In this image, the white places are the warmest, followed by red, yellow, green, and blue.  Astronomers take advantage of all kinds of radiation (including infrared) to learn about the universe.  Infrared detectors are also used for a variety of practical purposes here on earth.  For example, thermal (infrared) imaging may be used on buildings to detect where heat is being lost in the winter.
