Most astronomers think that a quasar's large redshift is an indication of its distance from us. As quasars are extremely distant, the light they emit is stretched to longer wavelengths and appears redshifted. This is known as cosmological redshift and is the result of the expansion of the universe. Therefore, a quasar's redshift can provide a measure of its distance from us.
