Hubble Space Telescope(HMT) - All You Need To Know

The Hubble Space Telescope (HST) is a soace 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  -

• Compton Gamma Ray Observatory
• Chandra X-Ray Observatory 
• Spitzer Space Telescope

The HST was built by the United States space agency NASA, with contributions from theEuropean Space  Agency 

The Space Telescope Science Institute  (STScI) selects Hubble's targets and processes the resulting data, while the Goddard Space Flight Center controls the spacecraft

With a 2.4-meter (7.9 ft) mirror, Hubble's four main instruments observe in the ultraviolet,visible and near infrared regions of the electromagnetic spectrum

Hubble is the only telescope designed to be serviced in space by astronauts

After launch by Space Shuttle Discovery in 1990, five subsequent Space Shuttle missions repaired, upgraded, and replaced systems on the telescope, including all five of the main instruments

The telescope is operating as of 2019, and could last until 2030–2040
