Hubble's law, also known as the Hubble–Lemaître law, is the observation in physical cosmology that galaxies are moving away from Earth at speeds proportional to their distance. In other words, the farther they are, the faster they are moving away from Earth. The velocity of the galaxies has been determined by their redshift, a shift of the light they emit toward the red end of the visible spectrum. WebEdwin Hubble and Red-Shifted Galaxies. He realized that galaxy spectra look a lot like stellar spectra, except more red-shifted. ... Recessional velocity is measured as the speed of light multiplied by red-shift. Recessional Velocity. Closer galaxies have smaller recessional velocities; further galaxies have longer recessional velocities ...
