The Webb Space Telescope is very powerful. It only released a photo of the cosmic wonder “Carina Nebula” at a distance of 76 million light-years last week. It also stated that this super-powerful telescope only uses a 68GB SSD to store photos. Now it is said that it is likely to be found in 135. In the Milky Way billions of years ago, human eyes have seen farther.

Scientists analyzing the first images from the James Webb Space Telescope, released only last week, said today that the Webb Space Telescope may have discovered the Milky Way that existed 13.5 billion years ago.
Rohan Naidu, a scientist at the Harvard-Smithsonian Center for Astrophysics, told AFP that the galaxy, called GLASS-z13, dates back 300 million years after the Big Bang, more than before The galaxy was discovered about 100 million years earlier.
“We may have observed the most distant starlight, farther than anyone has ever seen,” he said.
The farther an object is from us, the longer it takes for light to reach our eyes, so observing the distant universe is tantamount to gazing into the deep past.
The GLASS-z13 galaxy existed in the earliest days of the universe, but we don’t know its exact age, because GLASS-z13 could have formed at any time within the universe’s 300 million years of existence.
GLASS-z13 was discovered in “preliminary release” data from the Near Infrared Camera (NIRCam), the Webb Space Telescope’s primary imaging device, but was not announced when NASA released the first images last week. item message.
When transitioning from the infrared to the visible spectrum, GLASS-z13 appears as a red blob with a white center in a mass of distant cosmic images known as the “deep field.”
A global team of 25 astronomers, composed of Naidu and colleagues, have submitted their findings to scientific journals. Currently, the research results are stored and published on a “preprint” server with a warning that it has not yet been peer-reviewed, but it has generated a lot of buzz in the global astronomy community.
NASA chief scientist Thomas Zurbuchen tweeted: “The astronomical record is shaky and many more are on the way.”
He added: “Yes, I usually only cheer when scientific research has been peer-reviewed, but this seems to have a good chance of passing the scrutiny.”
