Astronomers using the James Webb Space Telescope have revealed the discovery of giant stars, which are presumed to be some of the first stars to form in the universe. These stars are about 10,000 times more massive than the Sun and have been called fossils, remnants of the early universe. The cores of these massive celestial bodies are much hotter than the stars already studied, due to the intense combustion of hydrogen at high temperatures.
Astrophysicist Corine Charbonnel of the University of Geneva said that thanks to data collected by the James Webb Space Telescope, they believe they have found the first evidence of the existence of these unusual stars. Researchers have identified between 100,000 and 1 million of these stars forming almost simultaneously in groups more than 12 billion years old.
Mark Gillis, a researcher at the University of Barcelona, explained that these groups of supermassive stars are nearing the end of their lives, as the average life expectancy of these giant stars is about two million years. Gillis pointed out that if the existence of massive stars is confirmed by future studies, this will represent a major advance in understanding globular clusters and the formation of giant stars in general, which will bring many important implications for science.
