JudyThe redshift effect was discovered by Edwin Hubble in the 1920s. He found that light from distant galaxies was shifted towards longer wavelengths, indicating that the galaxies were moving away from us. This discovery was a crucial piece of evidence for the expanding universe theory.

Who discovered red shift?
Red shift was discovered by astronomer Vesto Slipher in the early 20th century. He observed that the light from distant galaxies was shifted towards longer (redder) wavelengths, indicating that these galaxies were moving away from us. This discovery laid the foundation for our understanding of the expanding universe.
Who developed the red shift method?
The red shift method was developed by Edwin Hubble. He discovered that the light emitted by galaxies was shifted towards the red end of the spectrum, indicating that the universe is expanding.
Who discovered the Doppler red shift?
Christian Doppler, an Austrian physicist, is credited with discovering the phenomenon of the Doppler red shift in 1842. He observed that the pitch of sound waves from a moving object changes depending on the object's motion relative to the observer. His theory was later extended to light waves to explain the red shift observed in the spectra of distant galaxies.
Who discovered red shift in the starlight from distant galaxies?
The red shift in starlight from distant galaxies was discovered by Edwin Hubble in the 1920s. He noticed that light from these galaxies was shifted towards longer wavelengths, indicating that they were moving away from us and the universe was expanding.
Which astronomer discovered the red shift?
The first astronomer to discover that a galaxies red-shift was larger the further away it was was Edwin Hubble in the 1920s.The first scientist to describe red-shift in stars was actually Hippolyte Fizeau in 1848, though he was a physicist and not an astronomer.That light should be effected in this way was suspected by Christian Doppler (after whom "The Doppler Effect" is named) as early as 1842.
