In a historic moment, NASA’s James Webb Space Telescope found a galaxy called GLASS-z13 that existed 13.5 billion years ago. It is the oldest and most distant galaxy.
Space is filled with objects, galaxies, and what is unidentified and unexplored. And now, the James Webb Space Telescope has made history by finding a galaxy that existed 13.5 billion years ago. The galaxy is called GLASS-z13 and it is the oldest galaxy in the visible universe. An AFP report quoted a data scientist as saying: “Just a week after its first images were shown to the world, the James Webb Space Telescope may have found it. a galaxy that existed 13.5 billion years ago”.
The galaxy GLASS-z13 is dated to just 300 million years after the Big Bang, about 100 million years earlier than anything that has been identified before, Rohan Naidu of the Harvard Center for Astrophysics told AFP. . “We are likely looking at the farthest starlight that anyone has ever seen,” he said.
Dr. James O’Donoghue, planetary scientist, science communicator, and amateur animator who has previously worked with NASA, and is currently the Japan Aerospace Exploration Agency, tweeted about the Galaxy. “JWST is capable of breaking records, discovering a galaxy that existed when the universe was only 300 million years old! Light from GLASS-z13 took 13.4 billion years to reach us, but the distance is far away! between us is now 33 billion light years due to the expansion of the universe!” the tweet read. The tweet was reposted by NASA chief scientist Thomas Zurbuchen.
It is known that the further away objects are from us, the longer it takes for their light to reach us and the farther they are from Earth.
The exact age of GLASS-z13 is unknown as it could have formed any time within the first 300 million years. However, the galaxy is thought to exist in the earliest epoch of the universe. “GLASS-z13 was detected in so-called “early release” data from the observatory’s main infrared camera, called NIRcam – but the discovery was not revealed in the first set of images released by NASA announced last week,” AFP said.
The report adds, “As it translates from the infrared to the visible spectrum, the galaxy appears as a red blob with white in the center, as part of a broader image of the distant universe known as the universe. is “deep field”.
Naidu and colleagues – a team of 25 astronomers from around the world – submitted their findings to a scientific journal. Currently, the study is posted on a “pre-print” server, so it comes with the caveat that it has yet to be peer-reviewed – but it has stunned the global astronomy community.
“We’ve searched all the early data on galaxies with this very impressive signature, and these are the two systems with the most intriguing signatures to date,” Naidu quoted AFP as saying. One of these is GLASS-z13, while the other, not older, is GLASS-z11.
