The James Webb Space Telescope launched on December 25, 2021, begins to reveal more clearly the structure of the universe. Not a universe full of stars but of galaxies forms the relevant part of the information provided.
This has been made clear by employing gravitational lensing, to review certain of the universe.
In a recent research published by The Astronomical Journal, the north ecliptic pole was analyzed (within the project: Prime Extragalactic Areas for Reionization and Lensing Science (PEARLS), together with gravitational lensing (A gravitational lens is a distribution of matter -such as a cluster of galaxies- between a distant light source and an observer that is able to bend the light from the source as the light travels towards the observer, Source: wikipedia). Very distant galaxies were observed. A billion times more than can be seen with the naked eye, the light from these galaxies have traveled 13.5 billion years.
