  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. List of largest infrared telescopes - Wikipedia

    en.wikipedia.org/wiki/List_of_largest_infrared...

    Atmospheric windows in the infrared: much of this type of light is blocked when viewed from the Earth's surface. The largest infrared telescopes for infrared astronomy are listed in terms of diameter of primary mirror. The infrared spectrum with its longer wavelength than visible light has a number of challenges, especially for ground-based ...

    This visualization follows the Roman Space Telescope on its trajectory to the Sun–Earth Lagrange point L2.. The Nancy Grace Roman Space Telescope (shortened as Roman or the Roman Space Telescope, and formerly the Wide-Field Infrared Survey Telescope or WFIRST) is a NASA infrared space telescope in development and scheduled to launch to a Sun–Earth L 2 orbit by May 2027. [5]

    For launch in the 2030s, NASA is evaluating four possible designs: the Origins Space Telescope, Lynx X-ray Observatory, Habitable Exoplanets Observatory (HabEx), and Large UV Optical Infrared Surveyor . [38] Balloon-borne telescopes have been in use since the 1950s. A 20–30 meter balloon telescope has been suggested. [39]

    The NASA Infrared Telescope Facility (NASA IRTF) is a 3-meter (9.8 ft) telescope optimized for use in infrared astronomy and located at the Mauna Kea Observatory in Hawaii. It was first built to support the Voyager missions and is now the US national facility for infrared astronomy, providing continued support to planetary, solar neighborhood ...

  8. James Webb Space Telescope - Wikipedia

    en.wikipedia.org/wiki/James_Webb_Space_Telescope

    The Hi-Z telescope concept was developed between 1989 and 1994: [77] a fully baffled [b] 4 m (13 ft) aperture infrared telescope that would recede to an orbit at 3 Astronomical unit (AU). [78] This distant orbit would have benefited from reduced light noise from zodiacal dust. [78] Other early plans called for a NEXUS precursor telescope ...

  9. VISTA (telescope) - Wikipedia

    en.wikipedia.org/wiki/VISTA_(telescope)

    VISTA is a survey telescope working at infrared wavelengths, and is by far the largest telescope in the world dedicated to surveying the sky at near-infrared wavelengths. [2] The telescope has only one instrument: VIRCAM, the Vista InfraRed CAMera. This is a 3-tonne camera containing 16 special detectors sensitive to infrared light, with a ...
