Meet Quipu, a new contender for the largest known structure in the universe. It’s essentially a giant cluster of galaxy clusters stretching approximately 1.3 billion light-years long—more than ...

Quipu's immense length appears to break the previous record set by the "Sloan Great Wall," which stretches around 1.1 billion light years in a much more distant part of the universe.

Newly discovered Quipu, a superstructure in which galaxies group together in clusters and clusters of clusters, is the largest known structure in the universe in terms of length, scientists claim.

Quipu has the same mass as a staggering 200,000,000,000,000,000 copies of the sun, researchers say.

Quipu is the largest structure we've ever found in the universe. It and the other four superstructures the researchers found contain 45% of the galaxy clusters, 30% of the galaxies, 25% of the ...

In another shot to our cosmic ego, scientists have discovered a new superstructure, named Quipu, that stretches 1.39 billion light-years across and contains the equivalent mass of 200 quadrillion ...
