Infrared telescopes

Telescope Name Location Frequency Range Number of Antennas Key Scientific Objectives Notable Features
JWST (James Webb Space Telescope) Space (L2 orbit) 0.6–28 microns Space telescope with segmented mirror Galaxy formation, exoplanet atmospheres, star formation Highly sensitive, large primary mirror; superior resolution and sensitivity for infrared
Spitzer Space Telescope Space (NASA mission, decommissioned in 2020) 3–160 microns Space telescope with cryogenic cooling Exoplanet atmospheres, star formation, galaxy evolution Major infrared survey telescope; contributed to exoplanet and galaxy studies
WISE (Wide-field Infrared Survey Explorer) Space (NASA mission) 3.4–22 microns Space telescope with cryogenic cooling Asteroid detection, star formation, distant galaxies All-sky survey in infrared, detected brown dwarfs and distant galaxies
SOFIA (Stratospheric Observatory for Infrared Astronomy) Airborne (NASA and DLR) 0.3–1600 microns Modified Boeing 747 with a 2.7m telescope Star formation, molecular clouds, planetary atmospheres Airborne, can fly above most of the atmosphere for clearer infrared observations
AKARI Space (JAXA mission) 1.7–180 microns Space telescope with cryogenic cooling Galaxy evolution, star formation, interstellar medium Performed an all-sky infrared survey; focused on star-forming regions and interstellar clouds
IRAS (Infrared Astronomical Satellite) Space (NASA, UK, Netherlands mission, decommissioned) 8–120 microns Space telescope with cryogenic cooling Star formation, circumstellar disks, galaxy evolution First all-sky infrared survey; identified thousands of infrared sources
Herschel Space Observatory Space (ESA mission, decommissioned in 2013) 55–672 microns Space telescope with cryogenic cooling Star formation, molecular clouds, galaxy formation Largest infrared telescope in space; detailed observations of star-forming regions
UKIRT (United Kingdom Infrared Telescope) Mauna Kea, Hawaii, USA 1–5 microns Ground-based infrared telescope Star formation, planetary studies, infrared surveys Near-infrared telescope with wide-field survey capabilities, located at high altitude
Gemini South (Infrared capabilities) Cerro Pachón, Chile 1–28 microns Ground-based telescope with infrared instruments Exoplanets, star formation, Galactic center Advanced adaptive optics, part of the twin Gemini Observatories
IRTF (NASA Infrared Telescope Facility) Mauna Kea, Hawaii, USA 1–25 microns Ground-based telescope Planetary atmospheres, star formation, interstellar medium Primarily supports solar system research, especially infrared studies of planets
