![]() ![]() He was also hired by New Albany High School (New Albany, Indiana) in the autumn of 1913 to teach Spanish, Physics and Mathematics, and to coach basketball. ![]() The beloved high school teacher and coach Here he passed the bar examination and practised law half-heartedly for a year in Kentucky, where his family was then living. He studied Roman and English Law at Oxford and returned to the United States only in 1913. There, a promise made to his dying father, who never accepted Edwin's infatuation for astronomy, led him to study law rather than science, although he also took up Literature and Spanish. The Rhodes scholarĪ tall, powerfully built young man, Hubble loved basketball and boxing, and the combination of athletic prowess and academic ability earned him a Rhodes scholarship to Oxford. He finally obtained a degree in Mathematics and Astronomy in 1910. ![]() He paid his expenses by tutoring, working in the summer and, in his junior year, by obtaining a scholarship in physics and working as a laboratory assistant. This high school scholarship was also awarded to another student by mistake, so the money had to be halved and Edwin had to supply the rest. At his high school graduation in 1906, the principal said: "Edwin Hubble, I have watched you for four years and I have never seen you study for ten minutes." He paused, leaving young Edwin on tenterhooks a moment longer, before continuing: "Here is a scholarship for the University of Chicago." A promising studentĮdwin Hubble was born in Missouri in 1889, the son of an insurance executive, and moved to Chicago nine years later. When scientists decided to name the Space Telescope after the founder of modern cosmology the choice could not have been more appropriate. A man who eventually broke the promise made to his father and followed the path dictated by his passion.Īs a result of Hubble's work, our perception of mankind's place in the Universe has changed forever: humans have once again been set aside from the centre of the Universe. This sentence, written by Edwin Hubble recalling his youth, tells us a lot about the man. "I knew that even if I were second or third rate, it was astronomy that mattered." ![]() One of the goals of the Hubble Space Telescope, named for Edwin Hubble, was to determine H o, which it was able to do through years of observation and data.Edwin Powell Hubble - The man who discovered the cosmos One of the ongoing controversies surrounding Hubble’s Law is determining Hubble’s constant, Ho. (Receding velocity is how fast the galaxy is moving away from us.) We can determine a galaxy’s receding velocity by its redshift- most of the time . The law states that the more distant a galaxy, the greater the redshift. The third contribution is Hubble’s formulation of the redshift distance law in 1929, better known as Hubble’s Law. Hubble’s classification led to his Hubble Galactic Tuning Fork or Hubble Sequence - how he thought galaxies evolve. He classified these based on shapes: elliptical, spiral, and irregular, called a galaxy’s visual morphology. Second, Hubble was the first to classify galaxies based on what he observed, from 1922 to 1923. Yet Hubble’s observations of Cepheid variables in these galaxies and comparing them to Cepheids in the Milky Way led him to his controversial conclusion. This contradicted the view at the time the Milky Way was considered the Universe. Wilson Observatory in California, he demonstrated that some of these nebulae, like the Andromeda nebula, were actually objects – galaxies – far beyond our Milky Way galaxy.
