    Spitzer Space Telescope to retire in 2020 by - NASA

    Spitzer space telescope of NASA will be retiring on January 30th, 2020, assured by Jet Propulsion Laboratory in a statement. Spitzer is going to close permanently after about 16 years of exploring the cosmos in infrared light. By 2020, Spitzer space telescope will have worked for above 11 years beyond its chief mission.
    It was released in January 1983 as Infrared Astronomical Satellite, mutually developed by the USA, the Netherlands, and the UK, to conduct the 1st infrared survey of the sky. Spitzer is the only one of the Great Telescopes not released by the Space Shuttle, as was originally intended.
    More about Spitzer

    • Spitzer is a small but transformational telescope. It captures infrared light, which is often released by warm particles that are not quite hot enough to emit visible light.
    • Spitzer lifted the veil on secreted objects in nearly every corner of the universe, from a new ring around Saturn to annotations of some of the most distant galaxies known.
    • In 2017, the telescope discovered the presence of 7 rocky planets around the TRAPPIST-1 star.
    • In some cases, Spitzer's remarks were combined with data by other missions, with NASA's Kepler and Hubble space telescopes.
