The most ambitious view of JWST is now available for everyone | By Ethan Siegel | Start with an explosion! | May, 2025

This view represents more than 50% of the Cosmos-Web survey: the deepest vision of the universe ever acquired with JWST. It gives us our deepest wide field vision of the universe ever taken, revealing how galaxies and the largest structures throughout cosmic history evolve.. (Credit: ESA/Webb, NASA and CSA, G.

The Cosmos-Web survey is now complete, combining infrared data from JWST and Hubble. His spectacular views show us the universe as never before.

Our universe, today, contains Billions of galaxies with Sixthillones of stars.

Taking beyond the limits of any previous observatory, including all terrestrial telescopes on Earth and Hubble, JWST of NASA has shown us the most distant galaxies of the universe ever discovered. If we assign 3D positions to galaxies that have been sufficiently observed and measured, we can build a visualized fly from the universe, such as JWST CEERS data allow us to do here. At greater distances, compact stars formation galaxies are more common; At closer distances, the most diffuse and quiescent galaxies are the norm.

But 13,800 million years ago, There were none at all.

Following inflation, signatures are printed in the universe that are unequivocally inflationary. While the WBC provides an early “snapshot” of these characteristics, that is just a moment in history. By probing the wide variety of times/distances accessible to us during cosmic time, as with a large -scale structure, we can obtain information that would otherwise be dark from any unique snapshot.

Take time and severity for Modern cosmic structures To evolve.

This fragment of a structure formation simulation, with the expansion of the enlarged universe, represents billions of years of gravitational growth in a universe rich in dark matters. Over time, exaggerated matter groups become richer and more massive, which become galaxies, groups and groups of galaxies, while less dense regions that the average preferably pay their matter to the most dense surrounding areas. The “null” regions between the united structures continue to expand, but the structures themselves do not. (Credit: Ralf Kaehler and Tom Abel (Kipac)/Oliver Hahn)

To understand how it happened, we need to map the cosmic structure throughout history.

With the appropriate measurements taken in a variety of wavelength filters, distances and look times can be inferred for each galaxy taken in a deep field view of the universe. Galaxies can be classified into nearby containers, intermediate distance and great distance in the universe. The first galaxies found in the deepest images of the universe lead us just a few hundred million years after the Big Bang. (Credit: NASA, ESA Y Z. LIFE, F. Summers (STSCI))
