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. WebCHANGE IN REDSHIFT Although we have talked as if the redshift were a fixed parameter of an object, having a status analogous to its comoving distance, this is not correct.
