Biography of Edwin HubbleHubble was born in Marshfield (Missouri) on November 20, 1889. He entered Wheaton High School, where he actively participated in sports; His favorite sport was football, although he also participated numerous times in athletics competitions. On high school graduation day in 1906, the principal said, "Edwin Hubble, I have watched you for four years and have not seen you study for 10 minutes." He paused for an emotional moment for Edwin and continued, “Here's a scholarship to the University of Chicago.” In college he enjoyed working as a tutor, and in his senior year he worked as Robert Millikan's laboratory assistant. He obtained a scholarship in physics and received a distinction in sport for his participation in athletics, boxing and basketball. In 1910 Hubble graduated from the University of Chicago and in the same year he was awarded the Rhodes Scholarship, thanks to which he learned. Roman and English law at Queen's College, Oxford. A few years later he was made an honorary fellow of Queen's College. He returned to the United States in 1913, passed the relevant exams and practiced law without much enthusiasm for a year in Louisville, Kentucky, however, in 1914 he returned to the United States. University of Chicago to work after graduation with a clear goal: doctorate in astronomy He returned to the field of astronomy when he joined the Yerkes Observatory at the University of Chicago, where he received his doctorate in physics in 1917. George Ellery Hale, the founder and director of the Mount Wilson Observatory, near Pasadena (California), offered him a job in which he remained until his death. He was the first to use the Hale telescope at the Mount Palomar Observatory, where he revolutionized knowledge of the size, structure, and properties of the universe. Edwin Hubble thus became the most outstanding leader in the observational approach to cosmology..WORKEDWIN POWELL HUBBLEHis arrival. at Mount Wilson Observatory coincided with the completion of construction of the 2.54 m Hooker telescope, at that time the most powerful in the world. Observations made by Hubble in 1923 and 1924 with that telescope established beyond doubt that numerous nebulae existed previously. observed with less powerful telescopes they were not part of our galaxy as previously thought, but were rather galaxies different from the Milky Way. Hubble's research, in the explorations of the universe that he was able to carry out in his time, penetrated deeply into the realm of nebulae and gradually moved the limits of explored space.,
