Edwin Powell Hubble was an American astronomer known for his significant contributions to observational cosmology and extragalactic astronomy. His discovery in 1929 that the universe is expanding was a major breakthrough, leading to the acceptance of the Big Bang theory. Hubble's work also provided evidence for the existence of galaxies beyond the Milky Way and helped establish Hubble's Law.
