The Hubble Space Telescope (HST or Hubble) is a space telescope that was launched into low Earth orbit in 1990 and remains in operation. It was not the first space telescope, but it is one of the largest and most versatile, renowned as a vital research tool and as a public relations boon for astronomy.

The Ritchey-Chretien variant of Cassegrain reflector was invented around 1910, but not widely adopted until after 1950; many modern telescopes including the Hubble Space Telescope use this design, which gives a wider field of view than a classic Cassegrain.

First telescope designed to be repaired in space. USA (NASA) ESA Hubble Space Telescope [41] 2 July 1990: First time a spacecraft coming from deep space uses the Earth for a gravity-assist manoeuvre. ESA Giotto [42] 21 October 1991: First asteroid flyby (951 Gaspra closest approach 1,600 km). USA (NASA) Galileo: 1992 First confirmed observation ...
Two years of data from NASA's James Webb Space Telescope have now validated the Hubble Space Telescope's earlier finding that the rate of the universe's expansion is faster - by about 8% - than ...
They found that the new measurements were in line with those previous ones from the Hubble telescope. That rules out that the former telescope had made some inaccuracy – and indicate that it is ...
The Orbiting Astronomical Observatory 2 was the first space telescope launched 1968, [10] but the launching of Hubble Space Telescope in 1990 [11] set a milestone. As of 1 December 2022, there were 5,284 confirmed exoplanets discovered. The Milky Way is estimated to contain 100–400 billion stars [12] and more than 100 billion planets. [13]
