Scientists have found evidence of the universe’s first monster stars – around 13.1 billion years old – whose bodies broke apart and may have become part of ourselves and all the species.
By analyzing the magical light of clouds surrounding a distant quasar, a team of scientists from Japan, Australia and the United States discovered a “special mixture of heavy elements”which testifies to the existence of a hypothetical “monster”: First generation giant stars.
Leaf Scientific alert Explanatory quote from the research team: All stars that we see with the naked eye are classified as Population I or Population II, according to their age; in which population II stars are younger and contain more heavier elements than population II.

But I still have Population III – a hypothetical and older class of stars, whose existence coincides with the existence of the universe. To be able to observe them, people are forced to look at images of the world more than 13 billion years ago, that is to say, to look at something 13 billion light years away from us, because the The light coming out of it takes the same amount of time to reach Earth. Earth, giving humanity the ability to “look” into the past.
It was difficult, but by analyzing spectroscopic data, the new team indirectly captured light from a 13.1 billion-year-old quasar.
According to two of the study’s lead authors, astronomers Yuzuru Yoshii and Hiroaki Sameshima of the University of Tokyo in Japan, they calculated the prevalence of heavy elements that quasars release into the clouds. By wavelength intensity, a magnesium-iron ratio of 10 was found. “different” times from those of the solar system. Many heavy elements with other special relationships have also been determined.
With what appears in the clouds around the quasar, we can determine that the quasar is a supernova, meaning that the star died and exploded into a bright light, much brighter than an ordinary star. Quasar that’s what such things are called – something strong, like a star but not quite a star.
This dead star is much brighter than a normal star, so it was recorded. Not to mention the composition of the elements it possesses determined another hypothesis: they “pumped” a series of elements into the poor primitive universe with only hydrogen, helium and a little lithium.
The heavy elements created by Star Population III spread throughout star space and, after numerous cosmic evolutions, entered the bodies of rocky planets like Earth, according to many previous researches determined.
And the elements belonging to this ancient “monster” stellar lineage are the seeds of life, the answer to the eternal question: where do we come from?
