Infrared astronomy is a sub-discipline of astronomy which specializes in the observation and analysis of astronomical objects using infrared (IR) radiation. The wavelength of infrared light ranges from 0.75 to 300 micrometers, and falls in between visible radiation, which ranges from 380 to 750 nanometers , and submillimeter waves.
Infrared light is important to astronomy in three major ways. First, some objects are just better observed in infrared wavelengths. Some bodies of matter that are cool and do not emit much energy or visible brightness, like people or a young planet, still radiate in the infrared.
infrared astronomy, study of astronomical objects through observations of the infrared radiation that they emit. Various types of celestial objects—including the planets of the solar system , stars , nebulae , and galaxies —give off energy at wavelengths in the infrared region of the electromagnetic spectrum (i.e., from about one micrometre ...
