Astronomers say they’ve found the biggest structure in the universe and they named it the BOSS You think the Milky Way is big? Wait till you hear about the BOSS Great Wall. The BOSS is big. Really big. So big that when a star is born on one side of the BOSS, it takes a billion years for the light to reach the other side. What is the BOSS? It’s a wall. A Great Wall. The BOSS Great Wall is an immense complex comprising more than 800 galaxies and weighing 10,000 times as much as the Milky Way and other walls are just a measly pile of rocks on an insignificant planet in a remote part of space. It comprises four superclusters containing 830 galaxies, and it looms in space some 5 billion light-years away from Earth. For comparison the Laniakea supercluster that includes our own Milky Way galaxy, is less than half the size of the BGW. Indeed, the BGW is so big that some scientists question whether it can really be considered all one thing.
