Discover James Webb Telescope alien (JWST)of NASA, an “undiscovered” group of galaxies dating back to the early universe.
The telescope opened the door to a new chapter in astronomy by discovering a galaxy that formed only 350 million years following the Big Bang, making it the farthest starlight human has ever seen, according to the RT report.
This galaxy, identified with another galaxy that appeared 450 million years following the Big Bang, is exceptionally bright, indicating that it met only 100 million years following the event that ignited the universe 13.8 billion years ago..
And the galaxy bears a nameGLASS-z12as faint orange spots in the blackness of space, and would not have been seen without the James Webb Telescope’s powerful ability to look back in time with its infrared camera..
The team, led by the National Institute of Astrophysics in Rome, Italy, said the discovery resembled an “undiscovered country” of early galaxies that had hitherto been hidden away..
said Paola Santini, one of the authors of the paper, which was published in the journal Astrophysical Journal LettersThis is a whole new chapter in astronomy. It’s like an archaeological dig, where all of a sudden you find a lost city or something you didn’t know regarding. It’s just amazing.“.
It is estimated that the galaxy GLASS-z12 It is regarding 50 million years older than the previous record holder, the Galaxy GN-z11identified by the Hubble Telescope and the Keck Observatory in 2016, formed 400 million years following the Big Bang..
Given its properties, scientists suspect that the stellar cluster GLASS-z12 It lacks heavy elements and may even contain some of the stars known as Population IIIwhich burns at extremely high temperatures and consists only of primordial hydrogen and helium.
The ages of the two galaxies mean that they are markedly different from our own and the more mature galaxies that surround us today.
They are of a completely different shape, for example, they can be crushed into fields or disks much smaller than our galaxy.
They also turn gas into stars very quickly. It may have started producing stars only 100 million years following the universe appeared – roughly 14 billion years ago.
This indicates that the universe began to light up faster than expected, and it is still not clear why. It may be massive with many low-mass stars, or smaller but with far fewer bright stars.
Scientists hope to answer these questions and learn more through more detailed observations from the James Webb Telescope. The new discoveries come from data collected just days following it began its observations.
