Abstract
The Hubble Space Telescope ( HST ) is a space telescope that was carried into orbit by a space shuttle in 1990 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 was built by the United States space agency NASA, with contributions from the European Space Agency, and is operated by the Space Telescope Science Institute. It is named after the astronomer Edwin Hubble. The HST is one of NASA's Great Observatories, along with the Compton Gamma Ray Observatory, the Chandra X-ray Observatory, and the Spitzer Space Telescope. Space telescopes were proposed as early as 1923. Hubble was funded in the 1970s, with a Proposed launch in 1983, but the project was beset by technical delays, budget problems, and the Challenger disaster. When finally launched in 1990, scientists found that the main mirror had been ground incorrectly, severely compromising the telescope's capabilities. However, after a servicing mission in 1993, the telescope was restored to its intended quality Hubble's orbit outside the distortion of Earth's atmosphere allows it to take extremely sharp images with almost no background light Hubble's Ultra Deep Field image, for instance, is the most detailed visible light image ever made of the universe's most distant objects. Many Hubble observations have led t to breakthroughs in astrophysics, such as accurately determining the rate of expansion of the universe.
