astronomers NASA they made a Discover unprecedented pass James Webb Telescope After detection Galaxy 9422 “This may be the missing link in the evolution of galaxies between the universe’s first stars and the known and identified galaxies,” they assure.
a constellation It was discovered about a billion years after the Big Bang. The team speculates that “it was hit by so many photons from the star that it glowed unusually intensely.”

The practice of professional and critical journalism is a fundamental pillar of democracy. That’s why it bothers those who think they have the truth.
Star formation takes place within dense gas clouds that are producing large numbers of massive, hot stars, a remarkable singularity because it was predicted in the context of the first generation of stars in the universe, Astrophysics Home classified it as a “Population III star” according to the official website science.nasa.gov.
Senior Research Fellow at Oxford University, Alex Cameroninsisting that “This is exactly what the Webb telescope aims to reveal: completely new phenomena in the early universe that will help us understand how the history of the universe began.”.
In the local universe, a typical hot, massive star has a temperature between 70,000 and 90 degrees Fahrenheit, equivalent to 40,000 to 50,000 degrees Celsius. According to the team NASAthe stars in galaxy 9422 are hotter than 140,000 degrees Fahrenheit (80,000 degrees Celsius).

In this regard, theorists and researchers at the University of Chicago, Harry Katz, “It appears that these stars must be hotter and more massive than what we see in the local universe, which makes sense because the early universe was a different environment,” he explained.
Cameron, Katz and NASA scientists believe the conclusion is Galaxy GS-NDG-9422 Focusing on nebula light, rather than starlight, is the strongest starting point for future research.
