Humanity's most advanced space telescope, the James Webb Space Telescope (JWST), has made another astounding discovery. It may have detected "dark stars" that existed before the formation of ordinary stars, in the early stages of the universe. This is a type of star that scientists have been theoretically searching for over the past 15 years but had never observed.

According to reports, the JWST can observe the early stages of the visible universe. Three celestial bodies, which were identified as one of the earliest known galaxies in December of last year, are now believed to potentially be massive "dark stars."

The concept of "dark stars" was proposed in 2008. These stars are thought to have existed before the formation of ordinary stars in the early universe. "Dark stars" are believed to be composed predominantly of hydrogen and helium, with 0.1% of their mass in the form of dark matter. Instead of energy released through nuclear fusion like regular stars, "dark stars" would generate energy through the annihilation of dark matter. In this model, a "dark star" is a massive cloud of hydrogen and helium, with a mass at least a million times that of the Sun and about eleven times the luminosity of the Sun, with a diameter ranging from 4 to 2000 astronomical units.

Due to their lower surface temperature, "dark stars" would only emit infrared radiation and not visible light. As a result, they cannot be observed with the naked eye. However, utilizing the powerful infrared detection capabilities of the JWST, astronomers have managed to detect the farthest galaxies ever observed, and three of these celestial bodies are believed to be potential "dark stars."

One of them originated approximately 330 million years after the Big Bang, which occurred 13.8 billion years ago, while the other two formed around 370 million and 400 million years after the Big Bang. Experts state that although there is not yet enough data to make a definitive conclusion about these three bodies, the JWST may provide more comprehensive data on similar primitive objects, providing further evidence for the existence of "dark stars."
