WebJan 10, 2024 · Redshift indicates that an object is moving away from us. "Blueshift" is a term that astronomers use to describe an object that is moving toward another object or toward us. Someone will say, "That galaxy is blueshifted with respect to the Milky Way", for example. It means that the galaxy is moving toward our point in space. WebRedshift is also the name of the factor z indicating the relative change in wavelength due to the Doppler shift for a receding galaxy. The Doppler equation used for sound calculations …
