Redshift' is a key concept for astronomers.the term can be understood literally -the wavelength of the light is stretched,so the light seen as 'shifted' toward the red part of the spectrum.
'Blueshift ' A blueshift is any decrease in wavelength (increase in energy),with a corresponding increase in frequency, of an electromagnetic waves,the opposite effect is reffered to as redshift . In visible light, this shifts the colour from the red end of the spectrum to the blue end

Astronomy (from Greek: ἀστρονομία) is a natural science that studies celestial objects and phenomena. It uses mathematics, physics, and chemistry in order to explain their origin and evolution. Objects of interest include planets, moons, stars, nebulae, galaxies, and comets.
