Edwin Powell Hubble

  1. 1. Edwin Powell Hubble Nov. 29, 1889 – Sept. 28 1953 Contributed to the big bang Theory “At the last dim horizon, we search among ghostly errors of observations for landmarks that are scarcely more substantial. The search will continue. The urge is older than history. It is not satisfied and will not be oppressed.
  2. 2. Ethnicity and Personal Life • He was Caucasian • Edwin Powell was born in Marshfield, Missouri. His family moved to Chicago where he attended high school at Illinois State high. • Hubble was fascinated by both science and new and mysterious worlds and spent most of his childhood reading books of Jules Verne (20,000 leagues under the sea) and Henry Rider Haggard (King Solomon's Mines). • In 1913 Hubble set up to be a lawyer in Louisville Kentucky but it didn’t take long for Hubble to figure he wasn’t happy with his profession. He eventually started to study at the Yerkes Observatory to take on his passion of astronomy. • In 1917 Hubble received a doctorate in astronomy from the University of Chicago. After a tour duty in world war 1, Hubble took worked at the Mount Wilson Observatory
  3. 3. Discoveries and Contributions • Devised a classification system for the various galaxies he observed, sorting them by content, distance, shape, and brightness. • He noticed red shifts in the emission of light from the galaxies, seeing that they were moving away from each other at a rate constant to the distance between them. • From this, he was able to formulate Hubble’s Law in 1929, which helped astronomers determine the age of the universe and that the universe was expanding • We were also able to determine that if the universe was expanding outwards, it must have been coming from a central point, and that must have caused the expansion to begin with, giving us the Big Bang Theory.
  4. 4. Education and Positions Held • Went to Illinois State high • Also went to Oxford University • Fought in World War 1 • Worked in Mount Wilson Observatory in California • Left Mount Wilson 1942 to fight in World War 2 but thought his contribution to science was more helpful to his country . • After the war he return to Mount Wilson • Convinced his employers to create a better telescope then the current one. • It was design to further explore the galaxy • He continued to work at Mount Wilson and Mount Palomar until his death with cerebral thrombosis
  5. 5. Awards •Medal of Merit – exceptional conduct in providing outstanding service to local citizens •Elected Honorary Fellow of Queen’s College for his notable contribution to astronomy
