The James Webb Space Telescope hasn’t been scientifically active for even a month yet. But it’s already breaking all kinds of barriers. In a new paper still being peer reviewed – published July 20, 2022 on arXiv – a team of scientists claims that Webb has now captured the oldest galaxy we’ve ever seen.
So, just a week after its first images were shown to the world, the James Webb Space Telescope may have found a galaxy that existed 13.5 billion years ago. What is this galaxy? And how far it is? Let’s find out!
Welcome to Space World. In today’s video we are going to talk latest discovery made by the James Webb telescope about the oldest galaxy in our universe. So, if you want to know more about it then stay with us until the end of the video.
The Hubble Space Telescope held the previous galaxy discovery record back in 2016. It discovered GN-Z11, located in the direction of the constellation of Ursa Major, whose galaxy’s light was emitted 13.4 billion years previously, approximately 400 million years after the Big Bang. It also held the record for the capture of the most distant star ever recorded. Called Earendel, its light took 12.9 billion years to reach Hubble.
But with the Webb becoming fully operational as of last month, astronomers are confident it will usher in a new era of discovery. There are few times in history when we humans look at nature in an entirely new way, but Webb has already begun to write the next chapter in our cosmic story with its new images.
According to the latest information, James Webb telescope has found the oldest galaxy in our universe, and it is Known as GLASS-z13, the galaxy dates that back to 300 million years after the Big Bang. It is about 100 million years earlier than anything previously identified, Rohan Naidu of the Harvard Center for Astrophysics told AFP.
"We're potentially looking at the most distant starlight that anyone has ever seen," he said.
The more distant objects are from us, the longer it takes for their light to reach us, and so to gaze back into the distant universe is to see into the deep past. Though GLASS-z13 existed in the earliest era of the universe, its exact age remains unknown as it could have formed anytime within the first 300 million years.
GLASS-z13 was spotted in so-called "early release" data from the orbiting observatory's main infrared imager, called NIRcam - but the discovery was not revealed in the first image set published by NASA last week. When translated from infrared into the visible spectrum, the galaxy appears as a blob of red with white in its center, as part of a wider image of the distant cosmos called a "deep field."
Mr Naidu and colleagues - a team totaling 25 astronomers from across the world - have submitted their findings to a scientific journal. For now, the research is posted on a "preprint" server, so it comes with the caveat that it has yet to be peer-reviewed - but it has already set the global astronomy community abuzz.
