Wilson Archive Carnegie Institution of Washington Explanation: No person in history has had greater impact in determining the extent of our universe than Edwin Hubble . From proving that other galaxies existed to proving that galaxies move apart from one another Hubble 's work defined our place in the cosmos. Hubble lived from 1889 to 1953 and is shown above posing with the 48-inch telescope on Palomar Mountain and his famous pipe. In memory of his great work, the Orbiting Space Telescope was named after him . Today a great controversy rages on the rate of the universe's expansion, parameterized by a quantity known as Hubble's constant . A real live debate on this subject will take place in Washington, DC this April. Tomorrow's picture: Abell 3627 in the Great Attractor Archive Index Search Glossary ... USRA NASA Technical Rep.:

He taught high school for a year in Indiana and then returned to Chicago and astronomy. After obtaining his doctorate he spent his career, aside from army service in both world wars, at Mt. Wilson Observatory . In 1923 - 25 he identified Cepheid variables classification system of elliptical, spiral, and irregular galaxies, and to proof that they are distributed uniformly out to great distances. (He had earlier classified galactic nebulae.) Hubble measured distances to galaxies and with Milton L. Humason extended Vesto M. Slipher velocity-distance relation which, taken as evidence of an expanding Universe, is the basis of modern cosmology. Presentation of Bruce medal Babcock, H.D.

Hubble, Edwin Powell (b. Nov. 20, 1889, Marshfield, Mo., U.S.d. Sept. 28, 1953, San Marino, Calif.), American astronomer who is considered the founder of extragalactic astronomy and who provided the first evidence of the expansion of the universe. Hubble's interest in astronomy flowered at the University of Chicago, where he was inspired by the astronomer George E. Hale. At Chicago, Hubble earned both an undergraduate degree in mathematics and astronomy (1910) and a reputation as a fine boxer. Upon graduation, however, Hubble turned away from both astronomy and athletics, preferring to study law as a Rhodes Scholar at the University of Oxford (B.A., 1912). He joined the Kentucky bar in 1913 but dissolved his practice soon after, finding himself bored with law. A man of many talents, he finally chose to focus them on astronomy, returning to the University of Chicago and its Yerkes Observatory in Wisconsin. After earning a Ph.D. in astronomy (1917) and serving in World War I, Hubble settled down to work at the Mount Wilson Observatory near Pasadena, Calif., and began to make discoveries concerning extragalactic phenomena. While at Mount Wilson, Hubble discovered (1922-24) that not all nebulae in the sky are part of the Milky Way Galaxy, the vast star system to which the Sun belongs. He found that certain nebulae contain stars called Cepheid variables, for which a correlation was already known to exist between periodicity and absolute magnitude. Using the further relationship among distance, apparent magnitude, and absolute magnitude, Hubble determined that these Cepheids are several hundred thousand light-years away and thus outside the Milky Way system and that the nebulae in which they are located are actually galaxies distinct from the Milky Way. This discovery, announced in 1924, forced astronomers to revise their ideas about the cosmos.

EDWIN POWELL HUBBLE November 20, l889-September 28, 1953 from an article by N.U. Mayall in BIOGRAPHICAL MEMOIRS NAS 41 Edwin Hubble, by his inspired use of the largest telescope of his time, the 100 inch reflector on the Mount Wilson Observatory, revolutionized our knowledge of the size, structure, and properties of the universe. Hubble 's observations proved that galaxies are 'island universes". Hubble also outlined a classification system for galaxies that is still in use. His greatest discovery was the linear relationship between a galaxy's distance and the speed with which it is moving, known as the Hubble Constant. Edwin's mother was Virginia Lee James, from Virginia City, Nevada, and his father was John Powell Hubble, from Missouri, where Edwin himself was born in Marshfield on Novemeber 20, l889, during a visit to his grandparents. He liked and read many books, such as novels by Jules Verne and H. Rider Haggard, especially "King Solomon's Mines" . His father was affiliated with an insurance company; he had his office in Chicago and settled his family in surburban Wheaton.

There can be no doubt that future historians, writing about the scientific advances of this age will describe the 20th century as epoch-changing in giving us the first correct view of how the universe is organized. The principal cosmological problem of discovering the large scale content of the universe was solved observationally between 1920 and 1936. Hubble was a major figure in this development. Knowledge that galaxies mark the space and provide the means to measure it was gained by the first convincing analysis of new data on the nature of the nebulae - knowledge that came directly from the sky rather than by dialectic discussion or revelation. In Hubble's time, the centre of observational work on the new astrophysics, and later on what we know as cosmology, was the Mount Wilson Observatory. The two largest telescopes in the world were there and could be regularly used on these problems. With his appointment to the Mount Wilson staff in 1919, Hubble had continuing access to both the 60-inch and the 100-inch Hooker reflectors.

27. TIME 100: Edwin Hubble Up on the mountain, hubble encountered his greatest scientific rival, Harlow Shapley,who had already made his reputation by measuring the size of the Milky Way http://www.time.com/time/time100/scientist/profile/hubble02.html

NATION WORLD BUSINESS ARTS ... CURRENT ISSUE Hubble wasn't so sure. And in 1924, three years after Shapley departed to take over the Harvard Observatory, Hubble found proof to the contrary. Spotting a Cepheid variable star in the Andromeda nebula, Hubble used Shapley's technique to show that the nebula was nearly a million light-years away, far beyond the bounds of the Milky Way. It's now known to be the full-fledged galaxy closest to our own in a universe that contains tens of billions of galaxies. "I do not know," Shapley wrote Hubble in a letter quoted by biographer Christianson, "whether I am sorry or glad to see this break in the nebular problem. Perhaps both." (Hubble was not entirely magnanimous in victory. To the end he insisted on using the term nebulae instead of Shapley's preferred galaxies.) Hubble's scientific reputation was made almost overnight by his discovery that the universe is vast and the Milky Way insignificant. But he had already moved on to a new problem. For years, astronomers had noted that light from the nebulae was redder than it should be. The most likely cause of this so-called red shifting was motion away from the observer. (The same sort of thing happens with sound: a police car's siren seems to drop in pitch abruptly as the car races past a listener.) Hubble and his assistant, Milton Humason, began measuring the distances to these receding nebulae and found what is now known as Hubble's Law: the farther away a galaxy is from Earth, the faster it's racing away. Could it be that the universe as a whole is rapidly expanding? That conclusion was extraordinary, almost mind-blowing, yet seemed inescapable.

In 1929 he showed that galaxies are moving away from us with a speed proportional to their distance. The explanation is simple, but revolutionary: the Universe is expanding. Hubble was born in Missouri in 1889. His family moved to Chicago in 1898, where at High School he was a promising, though not exceptional, pupil. He was more remarkable for his athletic ability, breaking the Illinois State high jump record. At university too he was an accomplished sportsman playing for the University of Chicago basketball team. He won a Rhodes scholarship to Oxford where he studied law. It was only some time after he returned to the US that he decided his future lay in astronomy. In the early 1920s Hubble played a key role in establishing just what galaxies are. It was known that some spiral nebulae (fuzzy clouds of light on the night sky) contained individual stars, but there was no consensus as to whether these were relatively small collections of stars within our own galaxy, the '

Edwin P. Hubble (1889-1953) at Mt. Palomar Photo courtesy of the Archives, California Institute of Technology In the 1920s, there was a serious debate over whether galaxies were part of the Milky Way (our galaxy). Using the theoretical groundwork of Henrietta Swan-Leavitt and Harlow Shapley, Hubble's revolutionary observational work proved that galaxies are indeed "island universes". Hubble also outlined a classification system for galaxies that is still in use. His greatest discovery was the linear relationship between a galaxy's distance and the speed with which it is moving. The ratio of the two is known as the Hubble Constant . A key project of the Hubble Space Telescope is to find the value of the Hubble Constant to greater accuracy, in order to resolve several questions of cosmology. Hubble was born in Kentucky, attended college at the University of Chicago and studied law under a Rhodes scholarship at Oxford University. A change of heart led him to pursue astronomy, and he completed his PhD at Chicago's Yerkes Observatory in 1917. He had several other interests, among them boxing. His scientific career was punctuated by service in both World Wars. Edwin Hubble is recongized as having been one of the foremost astronomers of the modern era. Pete Reppert

Hubble, Edwin Powell US astronomer who discovered the existence of other galaxies outside our own, and classified them according to their shape. His theory that the universe is expanding is now generally accepted. Hubble discovered Cepheid variable stars in the Andromeda galaxy 1923, proving it to lie far beyond our own Galaxy. In 1925 he introduced the classification of galaxies as spirals, barred spirals, and ellipticals. In 1929 he announced Hubble's law, which states that the galaxies are moving apart at a rate that increases with their distance. Hubble was born in Marshfield, Missouri, and studied at Chicago and in the UK at Oxford. He briefly practised law before returning to Chicago to join Yerkes Observatory 1914. From 1919 he worked at Mount Wilson, near Pasadena, California. His data on the speed at which galaxies were receding (based on their red shifts) were used to determine the portion of the universe that we can ever come to know, the radius of which is called the Hubble radius. Beyond this limit, any matter will be travelling at the speed of light, so communication with it will never be possible. The ratio of the velocity of galactic recession to distance has been named the Hubble constant.

Encyclopedia Hubble, Edwin Powell Hubble, Edwin Powell, Slipher 's discovery that galaxies had strong shifts to the red end of their spectra, Hubble used the Cepheids in nearby galaxies to demonstrate that they lie far beyond the Milky Way. Because of an incorrect understanding of the Cepheids, this distance was vastly increased years later. He also suggested that the clusters of galaxies are distributed almost uniformly in all directions, although more recent studies show that clusters are combined into huge superclusters of galaxies: at this new level, however, the distribution appears to be even. He was the first to offer observational evidence to support the theory of the expanding universe, presenting his findings in what is now known as Hubble's law . With Milton Humason, Hubble classified the different types of galaxies including irregular galaxies, three types of spirals and barred spirals, and elliptical galaxies. Included in his writings are A General Study of Diffuse Galactic Nebulas Extra-Galactic nebulas Spiral Nebula as a Stellar System The Realm of the Nebulas (1936), and
