Galaktički sudar koji je stvorio Mlečni put: Posledice za formiranje Sunčevog sistema

New research suggests that the Milky Way, our galaxy, is the result of a collision between two galaxies. The collision between the Milky Way and a small galaxy known as Gaia-Sausage-Enceladus (GCE) took place 8-11 billion years ago. This collision brought in 50 billion solar masses and led to the formation of eight globular star clusters, along with accompanying gas and dust.

One of the most interesting consequences of this collision is the formation of a “bar” in the Milky Way. Astronomers have been intrigued by this shape and have embarked on research to determine if there is a connection between galaxy collisions and the formation of the “bar.” Using computer simulations, researchers have concluded that the formation of the bar would have been delayed by two billion years if it weren’t for the collision with GCE. Although the study does not prove that the collision directly caused the formation of the bar, it is clear that this event triggered the formation of this stellar structure.

Now the question arises: what impact did this galactic collision have on the formation of the Solar System and the conditions for life on Earth? While there are still no concrete answers to this question, these new findings open up avenues for further research and understanding of the evolution of our galaxy and planet.
