What was the exact method by which Hubble discovered the red-shift of distant galaxies?
I'm interested in learning about the exact method by which Hubble discovered the red-shift of distant galaxies. Can you tell me more about it?
Certainly, Edwin Hubble discovered the red-shift of distant galaxies through his use of the 100-inch Hooker telescope at Mount Wilson Observatory in California. He observed the light from galaxies and noticed that the spectral lines were shifted toward the red end of the spectrum, which is the phenomenon known as redshift.
