The Hubble Space Telescope was named after U.S. astronomer Edwin Powell Hubble (1889-1953).
Dr. Hubble studied the universe, helping scientists to better understand the formation and evolution of galaxies. The relationship, Hubble's law, was established based on Dr. Hubble's work.
Hubble's law states that the speed at which galaxies are receding from Earth (moving away) is proportional to their distance from us, or Recessional Velocity (V) = Hubble's constant (Ho) times distance (D).
Dr. Hubble's work in astronomy continues with the observations made by the Hubble Space Telescope. Read about it, and see it illustrated in dramatic images, all within the book "Hubble: A Journey Through Space and Time."
