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 ...
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 ...
New simulations reproduce high-redshift galaxies seen by JWST and propose a radical cosmological shift beyond ΛCDM. To simulate the universe with ...
New observations from the James Webb Space Telescope (JWST) suggest the cosmos may be much older than once believed. For ...
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 ...
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 ...
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.
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 ...
