A redshift can be created by several mechanisms; one that is of great interest to astronomers is the Doppler effect: if an object comes towards us, or goes away from us, the frequence of the light we receive from that object, changes.

What else can I help you with?
Will astronomers do all the redshifts of the 100 billion galaxies in the universe?
Perhaps in the future astronomers will do all the redshifts of the 100 billion galaxies in the universe.
Do quasars have a redshift?
Yes, very large redshifts.
Can astronomers get all 100 billion redshifts for all 100 billion galaxies in the observable universe?
No, because it will be impossible for astronomers to get all 100 billion redshifts for all 100 billion galaxies in the observable universe.
How can you list all the designations and redshifts of all 100 billion galaxies in the observable universe?
It is not possible to list all designations and redshifts of all 100 billion galaxies (cseligman.com/text/atlas/pgc00.htm)
Do quasars have large or small redshifts?
Quasars typically have large redshifts, which indicate that they are moving away from us at high speeds. This redshift is due to the expansion of the universe and can help astronomers determine the distance and age of quasars.
Will astronomers measure redshifts of 100 billion galaxies in the observable universe?
No. We do not have time to make so many measurements.
Is it impossible to do all the redshifts of the 100 billion galaxies in the observable universe?
Yes. To image, catalog, and calculate the redshift of each galaxy individually would take an extremely long time. In order to complete the work in 100 years we would need to measure redshifts at a rate of more than 30 galaxies per second.
The spectra of most galaxies show redshifts this means that their spectral lines?
have wavelengths that are longer than normal:)
What is the significance of quantized redshifts in the study of cosmology and the expansion of the universe?
Quantized redshifts are significant in cosmology because they provide evidence for the expansion of the universe. The quantization of redshifts suggests that galaxies are moving away from each other in discrete steps, supporting the idea of an expanding universe. This observation helps scientists understand the dynamics of the universe and its evolution over time.
The spectra of most galaxies show redshifts this means that their spectral lines are what?
The spectral lines of galaxies are redshifted, indicating that they are moving away from Earth. This redshift is typically a result of the expansion of the universe, causing galaxies to move further apart.
How does the expansion of the universe create redshifts?
As the universe expands, the space between galaxies also expands, causing their light to stretch out as it travels through this expanding space. This stretching of light waves results in redshift, where the wavelength of light increases, shifting it towards the red end of the spectrum.
What evidence is there that quasars are very far away?
All observed quasars have redshifts between 0.06 and 6.5. Using Hubble's law, it can be shown that they are between 780 million and 28 billion light years away (in terms of comoving distance). See related link for more information.
