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 ]
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 ...
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.
The near-infrared can be collected much like visible light; however, in the far-infrared and submillimetre range, telescopes can operate more like a radio telescope. For example, the James Clerk Maxwell Telescope observes from wavelengths from 3 μm (0.003 mm) to 2000 μm (2 mm), but uses a parabolic aluminum antenna. [ 20 ]
Notes on Hans Lippershey's unsuccessful telescope patent in 1608. The first record of a telescope comes from the Netherlands in 1608. It is in a patent filed by Middelburg spectacle-maker Hans Lippershey with the States General of the Netherlands on 2 October 1608 for his instrument "for seeing things far away as if they were nearby." [12] A few weeks later another Dutch instrument-maker ...
Gillet using the 2.1m telescope at Kitt Peak National Observatory in the mid-1970s. In 1975 he was part of the team selected by NASA that developed the Infrared Astronomical Satellite (IRAS). [2] [8] The project helped open up access to military infrared detector technology that had until then been classified. [1]
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 ]
1990 – Hubble 2.4m space Telescope launched, mirror found to be flawed; 1991 – Compton Gamma Ray Observatory satellite; 1993 – Keck 10-meter optical/infrared reflecting telescope begins operation, located at Mauna Kea, Hawaii; 1993 – Very Long Baseline Array of 10 dishes
