red shift

or red·shift (rĕd′shĭft′)
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.]


(Astronomy) a shift in the lines of the spectrum of an astronomical object towards a longer wavelength (the red end of an optical spectrum), relative to the wavelength of these lines in the terrestrial spectrum, usually as a result of the Doppler effect caused by the recession of the object. Compare: blueshift



a shift in the spectrum of a celestial object toward longer wavelengths, caused by the object's movement away from the viewer.
red′shift`ed, adj.
