Edwin Powell Hubble (November 20, 1889 – September 28, 1953) [1] was an American astronomer. He played a crucial role in establishing the fields of extragalactic astronomy and observational cosmology .
The following is a list of people who are not astronomers but made a contribution to the field of astronomy and astrophysics. Hans Bethe (1906–2005), (physicist) Niels Bohr (1885–1962), (physicist) Andreas Cellarius (Netherlands, Germany, 1596–1665), (cartographer) Freeman Dyson (1923–2020), (physicist) Albert Einstein (1879–1955 ...
Henrietta Swan Leavitt (/ ˈ l ɛ v ɪ t /; July 4, 1868 – December 12, 1921) was an American astronomer. [2] [1] [3] Her discovery of how to effectively measure vast distances to remote galaxies led to a shift in the scale and understanding of the scale and the nature of the universe. [4]
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-years away.
November 23 – Edwin Hubble announces his discovery that Andromeda, previously believed to be a nebula, is actually another galaxy, and that the Milky Way is only one of many such galaxies in the universe. [1] The Einstein Tower near Potsdam, Germany, designed by Erich Mendelsohn, becomes operational as an astrophysical observatory.
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.
His observations played a major role in the development of physical cosmology, including assisting Edwin Hubble in formulating Hubble's law. In 1950 he earned a D.Sc. from Lund University. [2] He retired in 1957. He discovered Comet C/1961 R1 (Humason), notable for its large perihelion distance. Due to merest chance, Humason missed discovering ...
The Great Observatories Origins Deep Survey, or GOODS, is an astronomical survey combining deep observations from three of NASA's Great Observatories: the Hubble Space Telescope, the Spitzer Space Telescope, and the Chandra X-ray Observatory, along with data from other space-based telescopes, such as XMM Newton, and some of the world's most powerful ground-based telescopes.
