Biography of Edwin Powell Hubble: Edwin Powell Hubble was an American astronomer who played a crucial role in establishing the field of extragalactic astronomy and is generally regarded as the leading observational cosmologist of the 20th century. He was born on November 20, 1889, in Marshfield, Missouri, and died on September 28, 1953. Hubble initially studied law but later switched to astronomy in graduate school. He received his Ph.D. in 1917 and went on to make several notable research and discoveries in the field of astronomy. Hubble is best known for his discovery of the expanding universe, which he observed through the redshift of light from distant galaxies. He also discovered that many objects previously thought to be clouds of dust and gas and classified as “nebulae” were actually galaxies beyond the Milky Way.
