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. It has a huge variance or margin of error that is not widely appreciated, and is evidently 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 hundreds of galaxies and billions of stars.
