light analysis 140,000 galaxies have revealed that their stars are heavier than previously thoughtwhich may change understanding of a wide range of astronomical phenomena.

This is the conclusion of a study published in The Astrophysical Journal by a team of researchers from The Astrophysical Journal Niels Bohr Institute, University of Copenhagen.

Since 1955, it has been assumed that the composition of stars in other galaxies of the universe is similar to that of hundreds of thousands of galaxies. Millions of Stars Inside Our Planet: A mixture of massive, medium and low mass stars. But with the help of observations of 140,000 galaxies across the universe and a wide range of advanced models, the team tested whether the same stellar distribution seen in the Milky Way applies elsewhere. The answer is no. Stars in distant galaxies are often more massive than those in our “local neighbourhood”. This discovery has a huge impact on what we think we know about the universe.

The researchers predicted that the size and weight of stars in other galaxies was as well Like our country for more than fifty yearsfor the simple reason that they could not observe them through a telescope, as they could stars of our galaxy.

Distant galaxies are billions of light years away. As a result, only the light from the most powerful stars reaches Earth. This has been a nuisance to researchers around the world for years as they have been unable to explain precisely how stars are distributed in other galaxies, an uncertainty that has forced them to believe they are distributed like stars in our Milky Way.

“We’ve only been able to see the top of the iceberg and have known for a long time that predicting the appearance of other galaxies like ours was not a particularly good guess. However, no one has been able to prove that other galaxies look like ours.” “Galaxies form different groups of stars. This study has allowed us to do exactly that, which may open the door to a deeper understanding of the formation and evolution of galaxies,” co-author Professor Charles Steinhardt says in a statement. studio.

In the study, researchers analyzed light from 140,000 galaxies using the COSMOS Catalog, a large international database of more than 1 million observations of light from other galaxies. These galaxies are scattered from the nearest point to the farthest point in the universe, with light from them having traveled twelve billion years before being observed on Earth.

According to the researchers, the new discovery will have a wide range of implications. For example, the reason why galaxies die and stop forming new stars remains unsolved. The new finding suggests that this can be explained by a simple trend.
