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 .
10 February 2002 – Solar Orbiter is launched to perform detailed measurements of the inner heliosphere and nascent solar wind, and perform close observations of the polar regions of the Sun 15 February 1845 – The Leviathan of Parsonstown , the world's largest telescope from 1845 to 1917, sees first light
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.
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.
The Newcomb Cleveland Prize of the American Association for the Advancement of Science (AAAS) is annually awarded to author(s) of outstanding scientific paper published in the Research Articles or Reports sections of Science.
The team nicknamed the star system Mothra due to its extreme magnification and brightness. Surprisingly, Mothra has appeared before, detected in Hubble observations nine years ago.
1924: Wolfgang Pauli: quantum Pauli exclusion principle; 1924: Edwin Hubble: the discovery that the Milky Way is just one of many galaxies; 1925: Erwin Schrödinger: Schrödinger equation (Quantum mechanics) 1925: Cecilia Payne-Gaposchkin: Discovery of the composition of the Sun and that hydrogen is the most abundant element in the Universe
The observational result of Hubble's law, the proportional relationship between distance and the speed with which a galaxy is moving away from us, usually referred to as redshift, is a product of the cosmic distance ladder. Edwin Hubble observed that fainter galaxies are more redshifted. Finding the value of the Hubble constant was the result ...
