Astronomers have discovered the most distant and oldest galaxy at the edge of the universe

Researchers have established that the galaxy GN-z11 is the most distant and oldest in the entire observable universe, defining its boundary.

Scientists continue to search for answers to questions related to the size and age of our universe. However, the huge scales and distances make such measurements much more difficult. A group of astronomers from the University of Tokyo claims to have identified the most distant cluster of stars, formed just a few hundred million years after the Big Bang..

They used the Keck I telescope in Hawaii to measure the redshift of the galaxy GN-z11, located 13.4 billion light years away. By identifying the chemical signatures of the ultraviolet light emanating from it, called emission lines, the team was able to improve the accuracy of the calculated distance (z-value) to a space object by a factor of 100..

This allowed astronomers to determine that this galaxy is the most distant and the oldest ever discovered. In fact, it can determine the boundary of the observable universe..
