An important astronomical event was observed on August 17, 2017. The event, called the merger or collision of two neutron stars, took place 130 million light-years away. In other words, the collision took place 130 million years ago, before human beings were on Earth, but its rays could only now reach us.
While the science of astronomy was not as advanced as today, we used to wonder, “Look! There are millions of celestial bodies in space; stars, planets, asteroids, and none of them collide, they all move on their own path.”
Today, however, we have learned that this is not exactly the case. Everything in space moves, galaxies pass through each other as they migrate, new galaxies are created during the transition, black holes merge, some stars collide, and some stars die out while new stars are born. While these great clashes and events are taking place, we witness the continuation of the magnificent order in the universe.
Today, scientists talk about 100 billion galaxies, each containing about 200 billion stars.
