"Web22 feb. 2024 · The "redshift" measurements that Hubble used to determine his law are based on looking at the spectrum of distant galaxies. That is, splitting the light coming from the object in its constituent colors (e.g. by passing it through a prism). If you look at such a spectrum, you will notice that certain lines (colors) are missing. " - How is redshift measured
