“Monster stars” are 10,000 times more massive than the Sun, detected for the first time

“Monster stars” are 10,000 times more massive than the Sun, detected for the first time

Scientists have been looking deep into space, looking back at the early days of the universe, and finding something really interesting.

Researchers using the James Webb Space Telescope have made a discovery indicating that some of the oldest stars ever formed in the universe were staggering in size, 10,000 times more massive than the sun.

says astrophysicist Corinne Charbonnel of the University of Geneva in Switzerland, in research published in Astronomy and astrophysics.

These features are massive collections of between 100,000 and 1 million stars known as globular clusters, which all have similar characteristics. Scientists estimate that they all formed at the same time.

They are remnants of the ancient universe and researchers have called them “fossils”.


The cores of these stars are much hotter than what we see in stars today, and scientists suggest that this may be due to the increased combustion of hydrogen at high temperatures.

It is believed that the smaller stars collided with the massive stars and enjoyed their energy. However, most of these cosmopolitan groups are now nearing the end of their lifespans.

“Global clusters are between 10 and 13 billion years old, while the maximum age of stars is 2 million years,” Mark Gillis, formerly at the University of Surrey but now at the University of Barcelona, ​​said in 2018. very early in the currently observable groups. Only indirect effects remain.

The researcher says: “If the scenario of massive stars can be confirmed by future studies, this will provide an important step for our understanding of globular clusters and for the formation of massive stars in general, with many important implications.”
