Infrared Astronomy
Related Category: Astronomy: General
study of celestial objects by means of the infrared radiation they emit, in the wavelength range from about 1 micrometer to about 1 millimeter.
Infrared
Infrared radiation is a form of electromagnetic radiation with wavelengths longer than those at the red-end of the visible portion of the electromagnetic spectrum but shorter than microwave radiation.
Infrared astronomy
Infrared astronomy is the branch of astronomy and astrophysics which deals with objects visible in infrared (IR) radiation. Visible radiation ranges from 400 nm (blue) to 700 nm (red).
Infrared Astronomy

Infrared Radiation:
Beyond the red end of the visible range, but at frequencies higher than those of radar waves and microwaves, is the infrared region of the electromagnetic spectrum.
InfraRed Astronomy is the study of Astronomical Objects in the InfraRed Spectrum. This is done mostly with satellite based telescopes, such as NICMOS on the HST, since the Earth's Atmosphere Filters IR Radiation.

Infrared radiation: the type of radiation that has wavelengths longer than the red end of visible light, but shorter than microwaves, with wavelengths between 1 and 100 micrometers. Infrared radiation is felt in the heat of the sun.
Infrared light Light just beyond the red edge of the visible spectrum is called infrared light. Its photons carry less energy than those of visible light. Our hands are better detectors of IR light than our eyes.
