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 100-inch (2.5 m) Hooker telescope at Mount Wilson Observatory that Hubble used to measure galaxy distances and a value for the rate of expansion of the universe. Edwin Hubble's arrival at Mount Wilson Observatory, California, in 1919 coincided roughly with the completion of the 100-inch (2.5 m) Hooker Telescope , then the world's largest.
Congress eventually approved funding of US$36 million for 1978, and the design of the LST began in earnest, aiming for a launch date of 1983. During the early 1980s, the telescope was named after Edwin Hubble. Hubble was originally intended to be retrieved and returned to Earth by the Space Shuttle, but the
It was used by Edwin Hubble to make observations with which he produced two fundamental results which changed the scientific view of the Universe. Using observations he made in 1922–1923, Hubble was able to prove that the Universe extends beyond the Milky Way galaxy, and that several nebulae were millions of light
After its launch, the Hubble Space Telescope had an attached PR campaign touting it as a scientific improvement over ground-based telescopes of the time. David Leckrone was Hubble's senior project ...
His discoveries of countless galaxies beyond the Milky Way revolutionised our perception of the universe that we live in. In 1990, a telescope was launched into the Earth's low orbit known as the Hubble Space Telescope, which was named after Edwin Hubble. [12] British astronomer Sir Martin Ryle studied at Oxford university in the 1930s. His ...
The Hubble Space Telescope Comparison between many space telescopes by diameter Overview of active and future telescopes (as of January 2021) This list of space telescopes ( astronomical space observatories ) is grouped by major frequency ranges : gamma ray , x-ray , ultraviolet , visible , infrared , microwave , and radio .
A galaxy's recessional velocity is typically determined by measuring its redshift, a shift in the frequency of light emitted by the galaxy. The discovery of Hubble's law is attributed to work published by Edwin Hubble in 1929, [2] [3] [4] but the notion of the universe expanding at a calculable rate was first derived from general relativity ...
