Redshift occurs when spectral lines of light or other electromagnetic radiation from astrophysical objects (like galaxies) show up in longer wavelengths than normal (in a laboratory experiment), apparently resulting in energy loss. It is the primary measuring “stick” used to determine cosmological distances. Redshift is measured several ways, in several wavelength bands, though surprisingly rarely in the visible light range, has a huge variance or margin of error that is not widely grasped, and is apparently caused by several independent phenomena.
Blueshift is the reverse – when spectral lines move towards shorter wavelengths apparently meaning an increase in radiation energy. Blueshift has been observed in radiation emitted by stars and galaxies moving towards us.
Importance: The interpretation of Spectral line Redshift as Universe expansion is the primary support for Big Bang models.
