The Spitzer Space Telescope (SST), formerly the Space Infrared Telescope Facility (SIRTF), is an infrared space telescope launched in 2003.
 It is the fourth and final of the NASA Great Observatories program.
George H. Rieke (born January 5, 1943), a noted American infrared astronomer, is former Deputy Director of the Steward Observatory and Regents Professor of Astronomy and Planetary Sciences at the University of Arizona in Tucson.
 He led the experiment design and development team for the Multiband Imaging Photometer for Spitzer (MIPS) instrument on NASA's infrared Spitzer Space Telescope, and currently chairs the science team of the Mid-Infrared Instrument for the James Webb Space Telescope (JWST).
The Great Observatories Origins Deep Survey or GOODS is an astronomical survey combining deep observations from three of NASA's Great Observatories: the Hubble Space Telescope, the Spitzer Space Telescope, and the Chandra X-ray Observatory, along with data from other space-based telescopes, such as XMM Newton, and some of the worlds most powerful ground-based telescopes.
The Extreme Ultraviolet Explorer (EUVE) was a space telescope for ultraviolet astronomy, launched on June 7, 1992.
 With instruments for ultraviolet (UV) radiation between wavelengths of 7 and 76 nm, the EUVE was the first satellite mission especially for the short-wave ultraviolet range.
 The satellite compiled an all-sky survey of 801 astronomical targets before being decommissioned on January 31, 2001.
 It re-entered the atmosphere on January 30, 2002.
IRrelevant Astronomy is a web series produced by NASA's Spitzer Space Telescope.
 Each episode explains a general science concept or reveals science news relevant to Spitzer.
 The "IR" in the title stands for "infrared", making the title refer to "infrared-relevant astronomy."
 The first episode launched on January 15, 2008 on the Spitzer Space Telescope website.
2MASS J22282889-4310262 is a brown dwarf discovered by The Hubble Space Telescope and The Spitzer Space Telescope in 2013.
 Through the uses of the Hubble and Spitzer, NASA astronomers were able to develop the most detailed 'weather map' for the brown dwarf utilizing different wavelengths of infrared light to show changing light patterns and different layers of material in the windstorms (the layers were generated because water and methane vapors infrared wavelengths).
 This observation was the first time that researchers were able to probe such variability at different altitudes of the body.
 On the outer layers of the star, gases condense into raindrop like particles made up of sand and iron which fall onto the interior.
 Researchers also determined that the object's temperature ranges from 1,100 to 1,300 degrees Fahrenheit (600 to 700 degrees Celsius).
The International Ultraviolet Explorer (IUE) was an astronomical observatory satellite primarily designed to take ultraviolet spectra.
 The satellite was a collaborative project between NASA, the UK Science Research Council and the European Space Agency (ESA).
 The mission was first proposed in early 1964, by a group of scientists in the United Kingdom, and was launched on January 26, 1978 aboard a NASA Delta rocket.
 The mission lifetime was initially set for 3 years, but in the end it lasted almost 18 years, with the satellite being shut down in 1996.
 The switch-off occurred for financial reasons, while the telescope was still functioning at near original efficiency.
The Infrared Science Archive (IRSA) curates the science products of NASA's infrared and submillimeter projects, such as the Spitzer Space Telescope, the Wide-field Infrared Survey Explorer (WISE), the Infrared Astronomical Satellite (IRAS), and the Two Micron All-Sky Survey (2MASS).
 IRSA also serves data from infrared and submillimeter European Space Agency missions with NASA participation, including the Infrared Space Observatory (ISO), Planck, and the Herschel Space Observatory.
 s of 2014 , IRSA provides access to more than 20 billion astronomical measurements, including all-sky coverage in 20 bands, spanning wavelengths from 1 micron to 10 millimeters.
 Approximately 10% of all refereed astronomical journal articles cite data sets curated by IRSA.
Lyman Strong Spitzer, Jr. (June 26, 1914 – March 31, 1997) was an American theoretical physicist, astronomer and mountaineer.
 As a scientist, he carried out research into star formation, plasma physics, and in 1946, conceived the idea of telescopes operating in outer space.
 Spitzer invented the stellarator plasma device and is the namesake of NASA's Spitzer Space Telescope.
 As a mountaineer, he made the first ascent of Mount Thor, with David Morton.
The Hubble Space Telescope (HST) is a space telescope that was launched into low Earth orbit in 1990 and remains in operation.
 Although not the first space telescope, Hubble is one of the largest and most versatile, and is well known as both a vital research tool and a public relations boon for astronomy.
 The HST is named after the astronomer Edwin Hubble, and is one of NASA's Great Observatories, along with the Compton Gamma Ray Observatory, the Chandra X-ray Observatory, and the Spitzer Space Telescope.
