| infrared radiation |
Radiation with wavelengths too long to be perceived by the human eye (that is, longer than 0.77 microns) and less than 1,000 microns. Room IR is infrared radiation in the 7.7-8.0 micron region and typical of that radiated from surfaces near room temperature.

| infrared radiation |
Electromagnetic radiation lying in the wavelength interval from 0.7 5m to 1000 5m (micrometers). Its lower limit is bounded by visible radiation, and its upper limit by microwave radiation. Most of the energy emitted by the Earth and its atmosphere is at infrared wavelengths. Infrared radiation is generated almost entirely by large-scale intramolecular processes. ...

is the part of the near-optical spectrum we perceive as heat rays, and these are emitted by stellar objects such as the Sun. IR is detected by satellites and ground telescopes, revealing the centers of galaxies, and gas clouds ('nebulae') where stars are being born.

| infrared radiation |
The heat energy that is emitted from all solids, liquids, and gases. In the context of the greenhouse issue, the term refers to the heat energy emitted by the Earth's surface and its atmosphere. Greenhouse gases strongly absorb this radiation in the Earth's tmosphere, and radiate some back towards the surface, creating the greenhouse effect.
