He James Webb Telescope (JWST) jointly operated by the NASA and the European Space Agency took a photograph of the Galaxy dimmer than universe , finding considered by specialists due to the complexity involved in identifying inconspicuous formations.
The constellation classified as JD1 It is considered the most distant in the cosmos by members of the National Aeronautics and Space Administration. whatHow did he manage to capture it according to the researchers?
The JWST space periscope characterized as “the most powerful ever built by mankind” Due to its technology, it allows analyzing infrared radiation, ancient light sources from the ether and even exoplanets.

The astronomers’ analysis of the discovery of the galaxy JD1
In a sense, the astronomer co-author of the study that made the discovery of JD1 public, Tommaso Treu, celebrated that “before the Webb telescopejust a year ago, we mightn’t even dream of confirming a Galaxy so weak”.
Its construction took place in 2007 and it was launched 14 years later, recently on December 25, 2021 aboard the Ariane 5 rocket from the French Guyana European Spaceport. It currently orbits the Sun at a distance of 1.6 million kilometers from Earthin a region known as the second Lagrange point.
A mysterious “music” on the hidden side of the Moon: what was heard on Apollo 10
He American astrophysicist and researcher at the University of CaliforniaGuido Roberts-Borsani highlighted the new official revelation by the NASA and analyzed that “the galaxies ultraweak as JD1, on the other hand they are much more numerous, so we believe that they are more representative of the galaxies that carried out the reionization process”.
What was the “epoch of reionization” according to NASA?
Explained by specialists from the US government agency, the “epoch of reionization”was the procedure through which the formation of the first galaxies at the beginning of the universe.
The James Webb telescope revealed the image of the first galaxies formed following the Big Bang
Between the first 400 and the first billion years, the neutral interstellar galactic medium was ionized by ultraviolet radiation emitted by the first stars shining in the first growing nebulae. An understanding of the physics of that historical moment on this sidereal phenomenon would connect it with modern knowledge regarding the ‘Big Bang’.
