Infrared Astronomy

The study of infrared energy produced by astronomical objects. Infrared is a form of energy with a longer wavelength and lower frequency than visible light. It is produced by relatively cool objects, such as planetary systems and clouds of interstellar dust. Earth's atmosphere absorbs most infrared energy, so it is best studied with telescopes in space or aboard high-altitude balloons or aircraft.
