Looking up at the night sky, it may seem our cosmic neighborhood is packed full of planets, stars and galaxies. But ...

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.

Throughout cosmic evolution, although dwarf galaxies are individually small, they are numerous and serve as the fundamental ...

It contains several examples of high redshift galaxies with various morphologies. NASA/STScI/CEERS/TACC/S. Finkelstein/M. Bagley/J. Kartaltepe ...

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.

When the new data came in, the teams were able to precisely measure the redshifts of both of these candidates, along with a few others. “Spectra are how you really confirm what a galaxy’s redshift is, ...

Scientists have long studied the vast and mysterious web-like structure of our universe, filled with clusters, filaments, and ...

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 ...

When the JWST began science operations in the summer of 2022, its deep observations of the universe quickly began turning up high-redshift galaxies. These are galaxies that seemed to have existed ...

In 2015, he says, the most distant galaxies known had redshift values of 8 or 9. But then the Hubble Space Telescope spotted a galaxy later named GN-z11 around redshift 11 and pushed the first ...
