Indeed, the Milky Way is just one component in the Local Group galaxy group, that itself is a component of the Virgo Super cluster. That, in turn, is part of the Laniakea Supercluster, a collection of what’s believed to be 100,000-150,000 galaxies gradually dispersing through the universe. Currently, it’s estimated to stretch approximately 520 million light-years.

Scientists believe that there are around 10 million super clusters in the observable universe. Actually understanding them and their structure, however, can be tricky. Just as the relatively low-density bridges and filaments that conjoin their components allow them to spread, so they can be tough to detect with traditional instruments like X-ray telescopes
