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 astronomy is founded on the detection and analysis of infrared radiation, wavelengths longer than red light and outside the range of our vision. The infrared spectrum is useful for studying objects that are too cold to radiate visible light, such as planets, circumstellar disks or nebulae whose light is blocked by dust.
Far infrared image of the Andromeda galaxy from the Herschel Space Observatory. Far-infrared astronomy is the branch of astronomy and astrophysics that deals with objects visible in far-infrared radiation (extending from 30 μm towards submillimeter wavelengths around 450 μm).
This glossary of astronomy is a list of definitions of terms and concepts relevant to astronomy and cosmology, their sub-disciplines, and related fields. Astronomy is concerned with the study of celestial objects and phenomena that originate outside the atmosphere of Earth. The field of astronomy features an extensive vocabulary and a ...
An infrared telescope is a telescope that uses infrared light to detect celestial bodies. Infrared light is one of several types of radiation present in the electromagnetic spectrum . All celestial objects with a temperature above absolute zero emit some form of electromagnetic radiation . [ 1 ]
Infrared astronomy deals with the detection and analysis of infrared radiation (this typically refers to wavelengths longer than the detection limit of silicon solid-state detectors, about 1 μm wavelength). The most common tool is the reflecting telescope, but with a detector sensitive to infrared wavelengths. Space telescopes are used at ...
The National Optical-Infrared Astronomy Research Laboratory (NOIRLab [pronunciation?]) is the United States' national facility for ground-based, night-time optical and infrared astronomy. It is funded by the National Science Foundation (NSF) and operated by the Association of Universities for Research in Astronomy (AURA), as a federally funded ...
The Infrared Astronomical Satellite (Dutch: Infrarood Astronomische Satelliet) (IRAS) was the first space telescope to perform a survey of the entire night sky at infrared wavelengths. [6] Launched on 25 January 1983, [ 3 ] its mission lasted ten months. [ 7 ]
