Dr Edwin Powell Hubble, who lends his name to the iconic Hubble Space Telescope, was one of the leading astronomers of the twentieth century.
Born 135 years ago today on 20 November 1889, his discoveries in the 1920s, including that countless galaxies exist beyond our own Milky Way, revolutionized our understanding of the universe, and our small place within it. He died in 1959, aged 63.
