Edwin Hubble was an astronomer who discovered in 1929 that there was a substantial excess of galaxies with [[redshift|red-shifted]] spectra than those with blue-shifted spectra, indicating that most galaxies are moving away from the Earth. These observations support scientific models of a "[[Big Bang]]" origin of the universe.  The [[Hubble Space Telescope]] is named after him.

'''Edwin Hubble''' (November 29, 1889 – September 28, 1953) was an [[American]] astronomer.

Among his contributions to the field of astronomy was the discovery that the vast majority of galaxies have [[redshift|red-shifted]] light, indicating that they are receding from the point of reference (Earth). These observations provided support for [[Albert Einstein|Einsteins']] [[General Theory of Relativity]], and support scientific models of a "[[Big Bang]]" origin of the universe.  The [[Hubble Space Telescope]] is named after him.
