2. Infrared telescope - Wikipedia

   en.wikipedia.org/wiki/Infrared_telescope

   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 ]

3. Infrared astronomy - Wikipedia

   en.wikipedia.org/wiki/Infrared_astronomy

   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.

4. Infrared - Wikipedia

   en.wikipedia.org/wiki/Infrared

   The sensitivity of Earth-based infrared telescopes is significantly limited by water vapor in the atmosphere, which absorbs a portion of the infrared radiation arriving from space outside of selected atmospheric windows. This limitation can be partially alleviated by placing the telescope observatory at a high altitude, or by carrying the ...

   The Mid-Infrared Instrument is a key instrument on the James Webb Telescope, and is able to see the faint light from the most distant stars and can see through dust and gas to spot stars being born.

6. James Webb Space Telescope - Wikipedia

   en.wikipedia.org/wiki/James_Webb_Space_Telescope

   The James Webb Space Telescope (JWST) is a space telescope designed to conduct infrared astronomy.As the largest telescope in space, it is equipped with high-resolution and high-sensitivity instruments, allowing it to view objects too old, distant, or faint for the Hubble Space Telescope. [9]

7. List of space telescopes - Wikipedia

   en.wikipedia.org/wiki/List_of_space_telescopes

   Positioning an optical telescope in space eliminates the distortions and limitations that hamper that ground-based optical telescopes (see Astronomical seeing), providing higher resolution images. Optical telescopes are used to look at planets, stars, galaxies, planetary nebulae and protoplanetary disks, amongst many other things. [150]

8. Chopping (astronomy) - Wikipedia

   en.wikipedia.org/wiki/Chopping_(astronomy)

   The Gemini Observatory is a set of two telescopes with one in Hawaii and the other in Chile. Both of these telescopes are infrared and both use chopping to eliminate background radiation. The telescopes chop their secondary mirrors at a rate of 3-5 Hz. Both observatories utilize tilt-tip correction to ensure that the image quality remains crisp.

9. IRAS - Wikipedia

   en.wikipedia.org/wiki/IRAS

   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 ]
