ESA - Space Science - What is 'red shift'? (546 words)
The red shift of a distant galaxy or quasar is easily measured by comparing its spectrum with a reference laboratory spectrum.
However, to be accurate, the red shifts observed in distant objects are not exactly due to the Doppler phenomenon, but are rather a result of the expansion of the Universe.
Doppler shifts arise from the relative motion of source and observer through space, whereas astronomical redshifts are 'expansion redshifts' due to the expansion of space itself.
COSMOLOGICAL RED SHIFT (3534 words)
The dependence of the frequency shift of on the cosine of the angle made with the gravitational field is an approximation because of the fact that the photon's trajectory changes.
This shift is proposed as the main cause of the cosmological red shift.
The periodicity of the red shift whereby distant stars seem to show distances which show sudden jumps [7] would seem to suggest that there are quantum components to the effect of gravity on the red shift.
