In one case, the photometric estimate of the redshift yielded 11.5, while the true redshift was less than 9. This is a difference of billions of light-years.

New data have revealed that the structures of galaxies in the early universe were much more diverse and mature than previously known. JWST's ability to see faint high redshift galaxies in sharper ...

The team also found five other galaxies with a redshift greater than 12, all of which exceed the redshift record set by JWST's predecessor and now colleague, the Hubble Space Telescope.

But measuring a distant object’s redshift, as powerful a tool as it is, isn’t enough to tell us everything we’d want to know about the Universe. In fact, if all we relied upon were redshift ...

The authors call this effect redshift difference. Rather than observing the redshift of a galaxy over decades, the team proposes looking for distant galaxies that are gravitationally lensed by a ...

In the 1970s he wrote a great deal about redshifts, the measurement by which one can determine the distances of objects like galaxies. He became fixated on a galaxy/quasar pair, NGC 4319 and ...

In 1929, Edwin Hubble noticed that distant galaxies looked redder than those nearby. Moreover, the further away they are, the redder they tend to look. This observation, known as redshift, allowed ...

photometric redshifts all lie above 1.9, with a median of 2.6 and a rms of 0.7. observed spectral range, and are extremely faint in the optical, with a median V = 26.6. Hence these galaxies would ...
