The James Web Space Telescope survey of a recently watched galaxy that should not be seen, as it only existed 300 million years after the Big Bang.

At that moment of space history, the universe was wrapped in neutral hydrogen and most objects and phenomena would not be visible until nearly a billion years later.

So far, researchers believe that light may come from the first stars to exist, or leaking from an over -grease black hole in the galactic nucleus. But the source remains unknown.
Deep in the universe are stars and galaxies and objects so far that the light we watch them produce billions of years. But there is an ancient light that we can see that we should not see at all.
As part of the James Web Space Telescope, an advanced deep extragalactic study (Jads), the NASA James Webb (JWST) space telescope, noticed something that should not be seen for us-galactic Jads-GS-Z13-1. This galaxy existed only 330 million years after the big explosion, which was still very phase of the babies of the universe.
Web managed to notice the GS-Z13-1 first, taking clear emissions from Liman-Alpha from the galaxy. These emissions are released when an electron in a neutral hydrogen atom is excited by a photon, which is energetic enough and is very common throughout the cosmos. But here’s the thing – they are very often discovered nowS Technically speaking, we should not be able to detect Liman-Alpha’s emissions of only 330 million years after the Big Bang.
Wrapped in neutral hydrogen, which absorbs light, the universe was mostly opaque in its worst days and remained so until about a billion years after its birth. It was not until the era of reinisation that the star from the stars became powerful enough to tear these atoms, to tear off its electrons, and to escape through the cloud. With all this neutral hydrogen now ionized – which means that it was positively charged as a result of the loss of its negatively charged electrons – the universe became transparent. This is the first moment we must be able to find Liman-alpha’s emissions.
But if that did not happen about a billion years after the Big Bang, how is it possible for scientists to see the GS-Z13-1 that existed when its light had to be darkened?
“The unexpected Liman-Alpha issue shows that the galaxy is a fruitful manufacturer and leak of ionizing photons,” NASA and ESA researchers said recently published in Journal NatureS “This suggests that massive, hot stars or actively galactic nucleus (AGN) created an early reionized region to prevent full completion [suppression] of Liman-alpha. “
The first stars may exist-known as population III or POP III stars-the source of light coming from the GS-Z13-1. These stars are thought to have been much more massive and glowing from the stars that now exist, and it would be an incredible discovery if it is confirmed that Liman-Alpha Emissions come from pop III stars. But there are some problems with this theory – the star table provided by the galaxy is not high enough to allow these stars, for example. There are some other emissions expected by POP III stars that are missing from the GS-Z13-1.
Researchers believe that another option is the over -fat black hole in the active galactic nucleus of the galaxy or AGN. Supermissive black holes accumulate and absorb so much matter that they throw out huge and extremely bright gas drains that scientists think could be sufficient to reinize only one section of the universe a little earlier.
So far, we are all still in the dark. But scientists are grateful for – if they are confused by the existence of – this ancient flashlight.
