November 20: On This Day – Edwin Powell Hubble’s Birthday
Edwin Powell Hubble born November 20, 1889
Until the mid 1920s, most scientists thought the Milky Way was the entire universe, and that the universe was static, unchanging.
Edwin Hubble’s discoveries changed our idea of the cosmos, showing first that the universe was much larger than previously thought, and second that it is expanding, getting larger and larger all the time.
Hubble showed we live in a universe of many galaxies
The Large Space Telescope was renamed as Hubble Space Telescope (HST) in honor of Edwin Hubble
