In 1929, the American astronomer Edwin Powell Hubble linked the red shift visible in the spectra of distant galaxies, to the constant expansion of the universe.

More than just a statement that the Universe is expanding, Hubble's Law is a quantitative, linear relationship between the distance to a galaxy, and the galaxy's redshift.

This is an important distinction, because with Hubble's law, you can determine the distance to a galaxy, just by measuring its redshift.
