The James Webb Space Telescope has made an unprecedented breakthrough by detecting three of the oldest galaxies in the universe. These galaxies, which began to form when the cosmos was only between 400 and 600 million years old, offer us a unique window into the first moments of creation.
The age of the universe: a fascinating mystery
The age of the universe is a subject that has captivated scientists and philosophers for centuries. Using various methods, they were able to calculate that the universe is approximately 13.798 billion years old, with a margin of error of 37 million years.
The James Webb telescope: a revolutionary tool
A team of researchers used the power of the James Webb Space Telescope to make this unprecedented discovery. Webb's extreme sensitivity made it possible to detect the dense gas surrounding these primitive galaxies, composed mainly of hydrogen and helium.
Kasper Heintz, lead author of the study and researcher at the Center for Cosmic Dawn (DAWN) at the University of Copenhagen, says: โWithout Webb, we would not be able to observe these early galaxies, let alone learn as much about them. on their training.
New avenues of research in astronomy
This new discovery adds to the achievements of the James Webb Space Telescope, which, since its launch in December 2021, has provided unprecedented images and data about the universe.
James Webb's discoveries open new avenues of research in astronomy and promise to revolutionize our understanding of the cosmos. As scientists continue to explore the data provided by this cutting-edge telescope, it is likely that more secrets about the origins and evolution of the universe will be revealed.
This important milestone in astronomy brings us one step closer to solving the mysteries that have intrigued humanity since time immemorial. The James Webb Telescope offers us the opportunity to glimpse the beginnings of the cosmos and better understand our place in the vast tapestry of the universe.
