NASA’s James Webb Space Telescope has detected evidence of three possible “dark stars” in the universe. Scientists have been searching for this type of star for more than 15 years, which many considered to be something only hypothetical, unnoticed.
In December last year, researchers initially identified the stars as some of the oldest known galaxies in the universe. However, they could be dark stars Really big. The study was Published in the journal Proceedings of the National Academy of Scienceson July 11.

According to experts, these Three stars It is made up almost entirely of hydrogen and helium – the two elements present during the early universe – with 0.1% of its mass in the form of dark matter. Moreover, the stars likely date back to the beginning of the history of the universe: 1) 330 million years later the great explosion; 2) 370 million years ago; 3) 400 million years after the phenomenon.
Possible dark matter in obscure stars
Unlike ordinary stars, which are powered by the fusion of atoms, like the Sun, those discovered by James Webb will contain some mysterious dark matter in their structure. This invisible matter is known based on gravitational effects on a galactic scale.

Among planets, stars, asteroids and other celestial bodies, there is a huge amount of elements of unknown nature in the universe, which gravitationally influence the dynamics of galaxies and the universe itself. This material falls into the category of “dark matter”. Until now, astronomers have not been able to say what they are.
Dark matter is thought to consist of compact, supermassive objects like black holes, or hypothetical, barely detectable particles known as inert neutrinos.
