Edwin Powell Hubble and the Expanding Universe

Edwin Powell Hubble (1889-1953) was an American astronomer who played a crucial role in establishing the field of extragalactic astronomy and is generally regarded as one of the most important observational cosmologists of the 20th century. Hubble is known for showing that the recessional velocity of a galaxy increases with its distance from the earth, implying the universe is expanding. Known as "Hubble's law", this relation had been discovered previously by Georges Lemaitre; a Belgian priest/astronomer who published his work in a less visible journal. Hubble is also known for providing substantial evidence that many formerly known "nebulae" were actually galaxies beyond the Milky Way. (from wikipedia.org)
