- n (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
- But the speeds indicated by the amount of redshift, some of which now equal 25,000 miles per second, have made many astronomers doubt.
- Instead, he turned to a spectrogram that he had taken from quasar 3C 48 and using Schmidt's redshift key discovered that 3C 48 was re ceding even faster than 3C 273.
- Timidly at first but more boldly of late, some astronomers have suggested other possible causes for the redshift, viz.

Because Type Ia supernovae are so bright, and so nearly uniform in their brightness, they are incomparable standard candles for studying the cosmos,says Perlmutter. "Comparing the brightness and redshift of distant Type Ia supernovae led...

No one has found a quasar with such a high redshift, with a redshift of 2.11, so close to the center of an active galaxy,said Geoffrey Burbidge.
