SPACE — The James Webb Telescope (JWST) discovered one of the oldest galaxies. Since its launch in December 2021, the James Webb telescope has discovered a galaxy from 13 billion years ago.
Findings published in the journal peer-review Science, including the smallest galaxies ever discovered. The galaxy probably formed 500 million years after the Big Bang.
The astronomers from the University of Minnesota who made the discovery say it could provide more information about galaxies that were born shortly after the universe emerged.

“This galaxy is far beyond the reach of all telescopes except the James Webb. “These first observations of distant galaxies are spectacular,” said Patrick Kelly, senior author of the paper Jerusalem Post.
Using the James Webb telescope, scientists try to travel back to the Big Bang. “We have never seen a galaxy when the universe was young at this level of detail. The volume of a galaxy is roughly one millionth that of the Milky Way, but we can see that it is still forming the same number of stars each year.”
Research author Hayley Williams added that the galaxies that existed when the Universe was in its early stages were very different from what is seen today. This discovery can help us learn more about the characteristics of these first galaxies, how they differ from nearby galaxies, and how earlier galaxies formed.
The James Webb Telescope is the newest telescope operated by NASA. James Webb is the most powerful telescope today.
James Webb is a new flagship space telescope to complement the Hubble telescope observations because Hubble has been used for more than 30 years. JWST can collect about 10 times more light than the Hubble Space Telescope.
