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 .
Edwin Hubble (father) [147] Monsignor Lemaître is considered "the Father of the Big Bang" and the first to derive what is now known as Hubble's law. Leavitt discovered Cepheid variables, the "Standard Candle" by which Hubble later determined galactic distances. Einstein's general theory of relativity is usually recognized as the theoretic ...
In 1929, the US astronomer Edwin Hubble published a paper in the Proceedings of the National Academy of Sciences of the United States of America showing, based on better and more abundant data than what Lemaître had had at his disposal in 1927, that, in the average, galaxies recede at a velocity proportional to their distance from the observer ...
In 1929, Edwin Hubble provided a comprehensive observational foundation for Lemaitre's theory. Hubble's experimental observations discovered that, relative to the Earth and all other observed bodies, galaxies are receding in every direction at velocities (calculated from their observed red-shifts) directly proportional to their distance from ...
George Ellery Hale (June 29, 1868 – February 21, 1938) was an American astrophysicist, best known for his discovery of magnetic fields in sunspots, and as the leader or key figure in the planning or construction of several world-leading telescopes; namely, the 40-inch refracting telescope at Yerkes Observatory, 60-inch Hale reflecting telescope at Mount Wilson Observatory, 100-inch Hooker ...
His father Ben Hoyle was a violinist and worked in the wool trade in Bradford, ... namely Hubble's red shift observations, ... with Edwin Salpeter (1997) Named after him.
Cosmological expansion was originally seen through observations by Edwin Hubble. ... The modern Big Bang theory, first advanced by Father Georges Lemaître, ...
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]
