has anomaly A few galaxies show blueshifts, the most famous being Andromeda galaxy, but most show redshifts, due to the expansion of the universe.has source: Croswell, K. 1995 The Alchemy of the Heavens, Anchor Books, 2001-09-27 09:29:47.0
has property wavelength shift is directly proportional to distancehas source: Croswell, K. 1995 The Alchemy of the Heavens, Anchor Books, 2001-09-27 09:29:47.0
has value the cosmological redshift as observed is the ratio of the radius of the Universe at the present epoch to the radius of the Universe at the time the radiation left the distant object.has source: Hopkins, J. 1976 Glossary of Astronomy and Astrophysics, University of Chicago Press, 2001-09-27 09:29:47.0

has definition The redshift due to the expansion of the Universe. Contrary to popular belief, this is not a Doppler shift. Most galaxies move away from us, but this is not the cause of their redshifts. Instead, as a light wave travels through the fabric of space, the universe expands and the light wave gets stretched and therefore redshifted.has source: Croswell, K. 1995 The Alchemy of the Heavens, Anchor Books, 2001-09-27 09:29:47.0
