The Hercules-Corona Borealis Great Wall is a massive galactic superstructure. It is the largest known celestial object thus far discovered, giving its epic name justice.

It was discovered in early November 2013 by a team of American and Hungarian astronomers, dethroning the previous record holder of largest object in the universe, Huge-LQG.
Little is known about this mysterious region, other than the fact that it’s yuge and may house billions of galaxies “depending on how you count them”.
