Where is the largest known structure in the universe located?

In cosmology, enormous galaxy groupings do not have simple single locations like planets or stars do. One well-known large structure is the Sloan Great Wall, a vast filament of galaxies discovered in Sloan Digital Sky Survey data. It is roughly 1.3 billion light-years from Earth in the direction of several northern constellations. More recently, astronomers have identified even larger candidate structures, but their exact status can be debated because cosmic structure definitions are complex.
