Francis raised her hand, "Edwin Powell Hubble was born on November 20, 1889 and died on September 28, 1953. He was a noted American astronomer, generally credited for discovering the redshift of galaxies and that fact that the universe is expanding. Nevetheless, this redshift discovery was actually been observed by Vesto Slipher in the 1910s, but the world was largely unaware of Vesto Slipher's work."

Francis continued, "An interesting fact about his youth is that in his younger days, he was noted more for his athletic abilities rather than his intellectual genius: he won seven first places and a third placing in a single high school meet in 1906. That year he also set a state record for high jump in Illinois."


Francis continued, "Regarding his studies, at the University of Chicago he concentrated on mathematics and astronomy which led to a B.S. degree in 1910. He spent the next three years as one of Oxford's first Rhodes Scholars, where he studied in the field of law and received the M.A. degree, after which he returned to the United States as a high school teacher and a basketball coach in New Albany, Indiana!"

Francis smiled, "After he earned his PhD the University of Chicago in 1917, in 1919 Hubble was offered a staff position by George Ellery Hale, the founder and director of Carnegie Institution's Mount Wilson Observatory, near Pasadena, California, where he remained until his death. Shortly before his death, Palomar's 200-inch Hale Telescope was completed, and Hubble was the first to use it.


After his arrival at Mount Wilson and using the 100-inch Hooker Telescope, then the world's most powerful telescope, Hubble's established that the fuzzy "nebulae" seen earlier with less powerful telescopes were not part of our galaxy, and were galaxies themselves, which he announced on December 30, 1924.

Subsequently, Hubble discovered the velocity-distance relation, now know as the Hubble's law, which led to the concept of the expanding universe. He also discovered the asteroid 1373 Cincinnati on August 30, 1935, and the asteroid 2069 Hubble is named for him."
