Sobre El Autor

As an undergraduate at the University of Chicago, Edwin Hubble was an exceptional boxer. His boxing abilities attracted the attention of a promoter who wanted to train him to fight the contemporary world heavyweight champion, Jack Johnson. Hubble, however, resisted the temptations of the boxing mostrar más ring and instead became a Rhodes scholar. He practiced law for a short time, and in 1914 he found his niche in astronomy, attending the Yerkes Observatory for graduate work. In 1919 Hubble became an astronomer at the Mt. Wilson Observatory, where he remained until 1948. From 1948 to 1953, he was an astronomer at Mt. Palomar Observatory. Hubble's research on galaxies led to his conclusion that galaxies are actually swarms of hundreds of billions of stars. Using his research and that of others (principally Milton Humason and Vesto M. Slipher), Hubble established the relation between redshift and distance, which showed that the universe is expanding. (Bowker Author Biography) mostrar menos

Basing his theory on the observation of the change in distanct galaxies, called red shift, Hubble showed that this is a Doppler effect, or alteration in the wavelength of light, resulting from the rapid motion of celestial objects away from Earth. In 1935, Hubble described his principal observations and conclusions in the Silliman lectures at Yale University. These lectures were published the following year as "The Realm of the Nebulae," which quickly became a classic work.… (más)
