[AFP = current affairs]The galaxy in the image captured by the James Webb Space Telescope may be 13.5 billion years old. Researchers who analyzed the data revealed to AFP on the 19th, a week after NASA released a series of images.
Rohan Naidu of the Harvard Center for Astrophysics told AFP, “The galaxy called GLASS-z13 is 300 million years after the Big Bang, so far. It seems to be about 100 million years older than the galaxy confirmed in. “
“What we see may be the light of the stars arriving from the farthest places humanity has ever seen.”
GLASS-z13 existed in the early days of the universe, but its exact nature is unknown. It is said that it may have been formed in about 300 million years after the Big Bang 13.8 billion years ago. The earliest universe that can be observed today is about 330 million years after the Big Bang.
The GLASS-z13 was observed by the infrared observation function “NIRcam” installed in the Webb Space Telescope. When infrared rays were converted into a visible spectrum, there was a red mass in a part of the image that captured the deep space region called “deep field”, and the central part appeared white.
A research team of 25 astronomers from around the world, including Mr. Naidu, submitted the results of this survey to a scientific journal as a pre-reviewed paper. It has already become a hot topic in the astronomy world around the world.
“I’m confident in this discovery,” said Naidu, who said another team of astronomers came to similar conclusions from the same data.[Translation edit]AFPBB News ｜ Terms of use
