Discovering Galaxy Superclusters: Where are we in the Cosmic Fabric? | Space Documentary

🌍 How are galaxies organized in our Universe? Are they structured and ordered, or are they randomly distributed? What laws govern the organization of galaxies? Many scientists, astronomers and astrophysicists have tried to answer these questions. In 2023, we have even more technical means to study the Universe, and all its mysteries no longer seem as unattainable as before... We now know that the Universe is made up of billions of stars, planets, comets, asteroids... And that all these celestial objects are indeed structured! First, stars are organized into galaxies. The Universe as we know it today has between 100 and 200 billion galaxies! Our own galaxy, the Milky Way, has 100 billion stars and extends over an area of around 100,000 light-years. The galaxies themselves then organize themselves into galaxy clusters. These are galaxies bound together by the force of gravity. Clusters of galaxies extend over some ten million light-years, and there are an estimated 25 billion of them in t
