Galaxy Cluster

Galaxy clusters are colossal groupings of galaxies bound together by gravity. These enormous structures contain hundreds or even thousands of galaxies, along with vast amounts of hot gas emitting X-rays and an invisible but influential presence of dark matter. A nearby example is the Virgo Cluster, which includes our own galaxy, the Milky Way.
Galaxy clusters rank among the largest known structures in the observable universe, surpassed only by even more enormous superstructures like superclusters and cosmic filaments, such as the Hercules-Corona Borealis Great Wall, a mind-bogglingly massive formation.
The size of galaxy clusters can vary greatly. Some are relatively compact, containing a few dozen galaxies, while others, known as Superclusters , encompass thousands of galaxies spread over hundreds of millions of light-years. These massive formations illustrate the hierarchical nature of the universe, where galaxies group into clusters, clusters into superclusters, and superclusters into immense cosmic filaments and voids, forming the vast cosmic web.

I am not good making articles, if they aren't fictional. So, i higly appreciate if you could modify this so it can be better.
Thanks for reading.
