There are several different kinds of redshift that we encounter in the universe. Those three are 'gravitational', 'doppler' and 'cosmological'. Before looking at two examples, it is best to have a ...

Wang and her team were able to identify the lensed images of two high-redshift galaxies. One, designated UNCOVER-z13 ("z" is shorthand for "redshift"), has a redshift of 13.079, confirming it to ...

Quantized redshift of cosmological objects would either indicate that they are physically arranged in a quantized pattern, or that there is an unknown mechanism for redshift that is not related to ...

But if astronomers continue to identify redshift z~7-10 galaxies with masses at the upper limit of their models, it will require a new understanding of how these galaxies form — or a revised ...

New simulations reproduce high-redshift galaxies seen by JWST and propose a radical cosmological shift beyond ΛCDM. To simulate the universe with ...

Cosmological redshift depends upon a galaxy's distance. Credit: NASA/JPL-Caltech/R. Hurt (Caltech-IPAC) In 1929 Edwin Hubble published the first solid evidence that the universe is expanding ...

In rapidly rotating black holes, the Ni shell might collapse into a torus, which could explain the striking images of supermassive black holes. New Cosmological Model Challenges the Big Bang ...

Redshift and blueshift are used by astronomers to work out how far an object is from Earth. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works ...

Images from the James Webb Telescope show the oldest star ever detected. ... “If we could see this object up close (without the cosmological redshift effect) it would look slightly blue.

The value of the cosmological constant is infamously the worst prediction ever made using quantum field theory; the math says it should be 120 orders of magnitude larger than what we observe.

Today we saw the release of the first batch of images taken by the James Webb Space Telescope. This is something we have both been waiting on for nearly 25 years. Back in those days, we were ...

The standard cosmological model invokes invisible mass—so-called "dark matter"—to explain why galaxies appear to spin faster than they should based on what they can be seen to contain.
