Edwin HubbleEdwin HubbleEdwin Powell Hubble (November 20, 1889 – September 28, 1953) was an American astronomer, noted for his discovery of galaxies beyond the Milky Way and the cosmic red shift. Edwin Hubble was one of the first to argue that the red shift of distant galaxies is due to the Doppler effect induced by the expansion of the universe. He was one of the leading astronomers of modern times and laid down the foundation upon which physical cosmology now rests. BiographyHubble was born to an insurance executive in Marshfield, Missouri and moved to Wheaton, Illinois in 1898. In his younger days, he was noted more for his athletic abilities rather than his intellectual genius: he won seven first places1 and a third placing in a single high school meet in 1906. That year he also set a state record for high jump in Illinois. His studies at the University of Chicago concentrated on mathematics and astronomy which led to a B.S. degree in 1910. He spent the next three years as one of Oxford's first Rhodes Scholars, where he studied in the field of law and received the M.A. degree, after which he returned to the United States as a high school teacher and a basketball coach in New Albany, Indiana. He served in World War I and quickly became Major. He returned to astronomy at the Yerkes Observatory of the University of Chicago, where he earned a Ph.D. in 1917. In 1919 Hubble was offered a staff position by George Ellery Hale, the founder and director of Carnegie Institution's Mount Wilson Observatory, near Pasadena, California, where he remained until his death. He also served in the US army during World War II. Shortly before his death, Palomar's 200-inch Hale Telescope was completed; Hubble was the first to use it. He died of a heart attack on September 28, 1953, in San Marino, California. His wife, Grace, did not have a funeral for him and never revealed what was done with his body - it was apparently Hubble's wish to have no funeral service and be buried in an unmarked grave. As of 2005, the whereabouts of his remains are unknown. DiscoveriesGalaxies exist beyond the Milky WayHubble's arrival at Mount Wilson in 1919 coincided roughly with the completion of the 100-inch Hooker Telescope, then the world's most powerful telescope. Hubble's observations in 1923–1924 with the Hooker Telescope established beyond doubt that the fuzzy "nebulae" seen earlier with less powerful telescopes were not part of our galaxy, as had been thought, but were galaxies themselves, outside the Milky Way. He announced this discovery on December 30, 1924. Hubble also devised a classification system for galaxies, grouping them according to their content, distance, shape, size and brightness. The universe is expandingThe 100 inch Hooker telescope at Mount Wilson Observatory that Hubble used to measure galaxy redshifts and discover the general expansion of the universe.Hubble was generally credited with discovering2 the redshift of galaxies. In 1929 Hubble and Milton Humason formulated the empirical Redshift Distance Law of galaxies, nowadays known as Hubble's law, which, once the redshift is interpreted as a measure of recession speed, is consistent with the solutions of Einstein’s General Relativity Equations for an homogeneous, isotropic expanding space. This led to the concept of the expanding universe. The law states that the greater the distance between any two galaxies, the greater their relative speed of separation. This discovery later resulted in the formulation of the Big Bang theory. Earlier, in 1917, Albert Einstein had found that his newly developed General Theory of Relatively indicated that the universe must be either expanding or contracting. Unable to believe what his own equations were telling him, Einstein introduced a cosmological constant (a "fudge factor") to the equations to avoid this "problem". When Einstein heard of Hubble's discovery, he said that changing his equations was "the biggest blunder of my life".3 Other discoveriesHubble discovered the asteroid 1373 Cincinnati on August 30, 1935. He also wrote The Observational Approach to Cosmology and The Realm of the Nebulae around this time. Nobel PrizeHubble spent much of the later part of his career attempting to have astronomy considered an area of physics, instead of being its own science. He did this largely so that astronomers could be recognized by the Nobel Prize Committee for their valuable contributions to astrophysics. This campaign was long unsuccessful and it appeared that Hubble's great achievements would remain unrewarded. Finally the Nobel Prize Committee decided that astronomy should fall under the description of physics. Unfortunately this occurred in 1953 - Hubble died before he could be given the prize, or even informed that he would receive it (his wife was informed after his death). HonorsAwards

Named for him. This campaign was long unsuccessful and it appeared that Hubble's great achievements would remain unrewarded. He died in Lexington and was interred in Lexington Cemetery. He did this largely so that astronomers could be recognized by the Nobel Prize Committee for their valuable contributions to astrophysics. He became vice president of the Elizabethtown, Lexington, and Big Sandy Railroad Company. Hubble spent much of the later part of his career attempting to have astronomy considered an area of physics, instead of being its own science. While turning down suggestions that he become active in politics again, he spoke out strongly against the Ku Klux Klan. He also wrote The Observational Approach to Cosmology and The Realm of the Nebulae around this time. He returned to Lexington in March 1869 after being granted amnesty and resumed the practice of law. Hubble discovered the asteroid 1373 Cincinnati on August 30, 1935. He continued to England, Canada, and England again. When Einstein heard of Hubble's discovery, he said that changing his equations was "the biggest blunder of my life".3. In an epic journey, filled with bizarre adventures, he and a small band made their way down the east coast of Florida, eventually sailing across the sea in a tiny boat to reach safety in Cuba. Unable to believe what his own equations were telling him, Einstein introduced a cosmological constant (a "fudge factor") to the equations to avoid this "problem". Breckinridge feared that he would be put on trial for treason by the United States government and resolved to flee the country. Earlier, in 1917, Albert Einstein had found that his newly developed General Theory of Relatively indicated that the universe must be either expanding or contracting. Eventually, the two became separated in the confusion of the journey. This discovery later resulted in the formulation of the Big Bang theory. Breckinridge continued to try to persuade Davis that further resistance would only lead to greater loss of life, but he also felt honor bound to protect the President from harm. The law states that the greater the distance between any two galaxies, the greater their relative speed of separation. Sherman. This led to the concept of the expanding universe. Johnston in his surrender negotiations with William T. In 1929 Hubble and Milton Humason formulated the empirical Redshift Distance Law of galaxies, nowadays known as Hubble's law, which, once the redshift is interpreted as a measure of recession speed, is consistent with the solutions of Einstein’s General Relativity Equations for an homogeneous, isotropic expanding space. Breckinridge went with Davis during the flight from Virginia as the Confederacy collapsed, while also assisting General Joseph E. Hubble was generally credited with discovering2 the redshift of galaxies. By so doing, he ensured that a full account of the Confederate war effort would be preserved for history. Hubble also devised a classification system for galaxies, grouping them according to their content, distance, shape, size and brightness. During the chaos of the fall of Richmond in early April, 1865, Breckinridge saw to it that the Confederate archives, both government and military, were not destroyed but rather captured intact by the Union forces. He announced this discovery on December 30, 1924. Breckinridge saw that further resistance on the part of the Confederacy was useless and worked to lay the groundwork for an honorable surrender, even while President Jefferson Davis fiercely desired to continue the fight. Hubble's observations in 1923–1924 with the Hooker Telescope established beyond doubt that the fuzzy "nebulae" seen earlier with less powerful telescopes were not part of our galaxy, as had been thought, but were galaxies themselves, outside the Milky Way. In early 1865, Breckinridge was made Secretary of War in the Cabinet of the Confederate States of America, a post he would hold until the end of the war. Hubble's arrival at Mount Wilson in 1919 coincided roughly with the completion of the 100-inch Hooker Telescope, then the world's most powerful telescope. He led the famous charge of the VMI cadets at the Battle of New Market on May 14, 1864. As of 2005, the whereabouts of his remains are unknown. He returned east in 1864, during the Overland Campaign, and was wounded again in the Battle of Cold Harbor. His wife, Grace, did not have a funeral for him and never revealed what was done with his body - it was apparently Hubble's wish to have no funeral service and be buried in an unmarked grave. He fought in many battles in the Western Theater, including the Battle of Shiloh, in which he was wounded. He died of a heart attack on September 28, 1953, in San Marino, California. He entered the Confederate Army during the American Civil War as a brigadier general and soon became a major general, originally commanding the First Kentucky (Orphan) Brigade. Shortly before his death, Palomar's 200-inch Hale Telescope was completed; Hubble was the first to use it. He was elected to the United States Senate and served from March 4, 1861 until expelled by resolution of December 4, 1861, for support of the rebellion. He also served in the US army during World War II. Douglas, the Northern Democrats' nominee. In 1919 Hubble was offered a staff position by George Ellery Hale, the founder and director of Carnegie Institution's Mount Wilson Observatory, near Pasadena, California, where he remained until his death. Breckinridge was an unsuccessful candidate for President in 1860, losing to Abraham Lincoln, and receiving more electoral votes than the other 2 major candidates, John Bell of the Constitutional Union Party, and Stephen A. in 1917. He was the youngest Vice President in US history at age 35, the minimum age required under the US Constitution. He returned to astronomy at the Yerkes Observatory of the University of Chicago, where he earned a Ph.D. He was elected Vice President in 1856 on the Democratic ticket with James Buchanan as President. He served in World War I and quickly became Major. Breckinridge did not run for reelection, and instead was nominated as Minister to Spain by President Franklin Pierce, but declined. degree, after which he returned to the United States as a high school teacher and a basketball coach in New Albany, Indiana. He was a member of the Kentucky House of Representatives in 1849 as a Democrat, and was then elected to the Thirty-second and Thirty-third Congresses (March 4, 1851 – March 3, 1855). He spent the next three years as one of Oxford's first Rhodes Scholars, where he studied in the field of law and received the M.A. Breckinridge was a major of the Third Kentucky Volunteers during the Mexican-American War in 1847 and 1848. degree in 1910. He was married to Mary Cyrene Burch in 1843. His studies at the University of Chicago concentrated on mathematics and astronomy which led to a B.S. He was admitted to the bar in 1840 and moved to Burlington, Iowa, but soon returned and began practice in Lexington. That year he also set a state record for high jump in Illinois. He graduated from Centre College in Danville, Kentucky, in 1839, later attended the College of New Jersey (now Princeton University), and then studied law at Transylvania University in Lexington. In his younger days, he was noted more for his athletic abilities rather than his intellectual genius: he won seven first places1 and a third placing in a single high school meet in 1906. Senator and Attorney General John Breckinridge, was born at "Cabell's Dale," near Lexington, Kentucky. Hubble was born to an insurance executive in Marshfield, Missouri and moved to Wheaton, Illinois in 1898. Breckinridge, grandson of U.S. . Representative, Senator from Kentucky, the fourteenth Vice President of the United States, and a Confederate general in the American Civil War. He was one of the leading astronomers of modern times and laid down the foundation upon which physical cosmology now rests.
