At the largest scales, galaxies are bound by mutual gravity into enormous structures. In a new survey, astronomers mapped out the nearby Universe and identified five major superstructures, including the largest ever seen, which they named "Quipu," after an Incan recording system. This vast structure is about 1.4 billion light-years long, with 240 quadrillion times the mass of the Sun and contains 68 major galaxy clusters, each of which has thousands of galaxies.
