Scientists believe the Milky Way is much older than currently believed.
Using existing observational data, astrophysicists participating in the CIELO project, which brings together scientists from Argentina, Chile and Spain, made an interesting assumption. Forbes believe our galaxy is 2 billion years older than currently believed.

The aim of the CIELO project is to create a virtual universe to study how galaxies form and, in particular, how the Milky Way is formed. Two of the project’s astrophysicists, Patricia Tissera and Susana Pedrosa, use numerical simulations to create a virtual universe composed of binary codes, literally zeros and ones. The results of these numerical experiments are then compared with space observations.

Scientists explain that they took the speed, mass distribution, temperature, chemical elements, and gas surrounding the stars in the stars and compared them with observations. This allows you to understand whether the correct hypotheses exist or whether they need to be changed.
As for the Milky Way, it is assumed that our galaxy appeared about 10 billion years ago. On the one hand, it is an ordinary spiral galaxy, on the other hand, it is rare that it has not undergone large-scale mergers with other galaxies in the last few billion years. It is assumed that the entire morphology of the Milky Way has changed little over billions of years. Although in a few billion years the Milky Way will face a terrible catastrophe, because our galaxy will merge with the neighboring Andromeda galaxy.
At the same time, astrophysicists believe that modeling and observational data indicate that the Milky Way may actually be between 10 billion and 12 billion years old. Because there may be stars in our galaxy that are much older than the Milky Way, and they may be almost as old as the Universe itself, which is 13.8 billion years old.
As I already wrote Focus4 years ago, astronomers discovered a strange wave-like structure consisting of gas and star clusters 500 light-years away from us. The entire structure is 9,000 light-years long. New research has revealed an important feature of this structure. It turns out that it simply moves around the center of the Milky Way and coils like a snake, that is, it makes wave-like movements.
Moreover Focus He wrote that astronomers have confirmed the primary source of gold in space. For the first time, scientists have been able to confirm that metals heavier than iron cause collisions between dead stars, leading to kilonova explosions.
