Redshift vs blueshift astronomy
Web22. nov 2015 · The wavelengths of the light will appear longer than they really are. Longer wave lengths of light are characteristics of the red end in the spectrum. So the spectrum … WebRedshift and blueshift refer to the change in the frequency (or wavelength) of a light wave depending on whether an object is moving towards or away from us. When an object is moving away from us, the light from the object is said to be redshifted, and when an object is moving towards us, the light is blueshifted.

Galaxies further away are speeding away from us faster than those close to us, hence having a stronger redshift effect. Web15. sep 2024 · These red or blue shifts tend to mask any cosmological redshift for nearby galaxies, which redshift is in any case trivial. The Andromeda galaxy, for example, is slightly blue shifted, as it is coming towards us and is 'only' 2.5 million light years away.
