Can you see the red dot on the picture? Well, that’s were our galaxy is! That’s us. This „creature“ is called Laniakea (it means ‘immeasurable heaven’ in hawaiian). It’s a massive supercluster that couple of astronomers discovered. Basically, it’s a web of galaxies put together as one.
Laniakea Supercluster, extends more than 500 million light-years and contains 100,000 large galaxies. Galaxies are not spread randomly throughout the universe. Instead, they clump in groups, such as the one Earth is in, the Local Group, which contains dozens of galaxies. In turn, these groups are part of massive clusters made up of hundreds of galaxies, all interconnected in a web of filaments in which galaxies are strung like pearls.
Around Laniakea are four neighbouring superclusters known as Shapley, Hercules, Coma and Perseus-Pisces. It may not be stamped in your passport, but everyone on Earth is now officially a citizen of Laniakea.
