Examples of redshift
redshift
Although both effects contribute, the redshift is the less important of the two.
From the en.wikipedia.org
A distortion of very-high-redshift galaxy number counts by gravitational lensing.
From the sciencedaily.com
He discovered a relationship between the redshift of a galaxy and its distance.
From the en.wikipedia.org
Gravitational redshift of galaxies in clusters as predicted by general relativity.
From the sciencedaily.com
The larger the redshift, the younger the universe in which the galaxy is observed.
From the sciencedaily.com
The three quasars have the same redshift, hence, are at the same distance from us.
From the sciencedaily.com
It is designed to precisely measure several hundred high-redshift supernovae.
From the en.wikipedia.org
The accessible redshift range corresponds on average to about 10 billion years ago.
From the sciencedaily.com
Anything that has a redshift of even 1 percent has to be outside the galaxy.

- Red shift: (astronomy) a shift in the spectra of very distant galaxies toward longer wavelengths (toward the red end of the spectrum); generally interpreted as evidence that the universe is expanding
- In physics (especially the physics of astronomical objects), redshift happens when light seen coming from an object is proportionally shifted to appear more red. Here, the term "redder" refers to what happens when visible light is shifted toward the red end of the visible spectrum. ...
- Redshift are a British electronic music group.
- Redshift is planetarium software created by Maris Multimedia. It runs on Microsoft Windows.
- The Redshift is the fourth album from the Finnish melodic death metal band Omnium Gatherum. It is the band's second release for the Candlelight Records label. The album features a number of creative aspects not yet attempted by the band.
- This is the name given to the apparent change in the wavelength of light due to the expansion of the universe. Scientists know what the spectrum of a galaxy should look like (based on the laboratory spectra of light emitted from known elements). ...
- A change in the frequency or wavelength of light. This can arise from motion of the source (Doppler shift), expansion of space, or strong gravitational fields.
- When a radiating object moves away from us, we observe a redshift in its light, or the light waves it emits are getting longer (shifting to the red part of the spectrum).
- A shift in the lines of an object's spectrum toward the red end. Redshift indicates that an object is moving away from the observer. The larger the redshift, the faster the object is moving.
