The Milky Way has no numerical date

Some small galaxies have collided with the Milky Way. Similar clashes still occur in the future, but they cannot destroy the Milky Way as predicted by many scientists.

Space.com said, about 20-25 small galaxies revolving around the Milky Way. In fact, they are small star groups, so they do not cause a big impact when hitting the Milky Way. However, some pessimists argue that if many satellite galaxies collide with the Milky Way at the same time, our galaxy may be torn apart.

To understand the problem, Ohio University astronomers use a computer model to simulate the galaxy's collision with satellite galaxies. The model shows that such clashes only create thin disk-shaped material belts around small galaxies, not tearing the Milky Way.

' Our models show that spiral galaxies like the Milky Way are not destroyed when they collide with satellite galaxies ,' said Stelios Kazantzidis, the leader of the research team.

Although the Milky Way is not in danger due to collisions with dwarf galaxies, astronomers predict it will clash with Fairy Female - the closest spiral galaxy and also roughly the same size. The encounter can happen in a few billion years.

Fortunately, collisions between two galaxies will not put an end to civilization on earth. All stars in galaxies are so far apart that they will not crash into each other when that event takes place. So the sun (a star) continues to exist and illuminate the planet. In fact, the merger between the two galaxies also creates many new stars.
