n.
An increase in the wavelength of radiation emitted by a receding celestial object as a consequence of the Doppler effect.

[From the fact that the longer wavelengths of light are at the red end of the visible spectrum.]

red shift

An increase in the wavelength of radiation emitted by a receding celestial body as a result of the Doppler effect. Objects appear reddish because the longer wavelengths of light are at the red end of the visible spectrum. Compare blue shift. See Note at Doppler effect.
