Wiktionary
n. (context physics English) A change in the wavelength of light, in which the wavelength is shorter than when it was emitted at the source.
Wikipedia
A blueshift is any decrease in wavelength, with a corresponding increase in frequency, of an electromagnetic wave; the opposite effect is referred to as redshift. In visible light, this shifts the color from the red end of the spectrum to the blue end.
In astronomy, a blueshift is a decrease in electromagnetic wavelength caused by the motion of a celestial object toward an observer.
