German experts calculate the age of the Milky Way

The Max Planck Institute for Astronomy in Heidelberg, Germany, reported this Friday that the Milky Way is made up of three structural levels, with different ages for each region, and the oldest was formed 13,000 million years ago.

According to the institution, the galaxy was generated around 800 million years after the great explosion, called the Big Bang, the initial point at which matter, space and time were formed.

“The resulting image is remarkably clear. By classifying the stars by age and chemical composition, astronomers were able to at least read the summary history of the adolescent galaxies like an open book, and with the age information, they were able to tell when they had occurred. the different stages”, the entity pointed out.

Likewise, the experts indicated that the teams analyzed the subgiant celestial bodies, in which the energy internally stopped its generation inside the nucleus to do so in its outer shell, in a short period of time, which made it possible to determine the age with accuracy. .

In the early stages, the Universe was made up of compounds such as hydrogen and helium, while the rest of the chemical elements, mostly metallic, were generated inside the stars.

After their death, they were expelled into space, allowing the incorporation of metallic components to the new celestial bodies that arise.

“That’s the newly refined reconstructed version of our galaxy’s history. It’s hard to put reliable dates to events in the cosmic history of the home galaxy. The new study has succeeded in constructing a detailed timeline of our galaxy’s teenage years.” galaxy is a great progress”, stressed the German Institute.
