Scientists discovered the largest structure in the universe, which is unlike anything seen before.
The universe contains many types of massive formations, from galaxy clusters to superstructures.
Astronomers have spent years mapping these arrangements to help shape our understanding of how matter is spread across space.
Along the way, they're piecing together how cosmic evolution unfolds and adding evidence to how the universe expands.

Recently, a team of scientists announced a giant collection of galaxy clusters that's shattered previous records.
The study was led by Hans Böhringer from the Max Planck Institute for Extraterrestrial Physics (MPE) in collaboration with researchers from Spain and South Africa. Using data from the ROSAT X-ray satellite survey, the researchers identified singled-out galaxy clusters that were emitting high-energy radiation.
With this, the researchers constructed a 3D map of our cosmic surroundings - and what they found was extraordinary.
The study shows that no matter how much we learn about the universe, there are still surprises waiting about how matter arranges itself across inconceivable distances.
“If you look at the distribution of the galaxy clusters in the sky in a spherical shell with a distance of 416 to 826 million light-years, you immediately notice a huge structure that stretches from high northern latitudes to almost the southern end of the sky,” explained Böhringer.
Quipu - named after the ancient Incan system of knotted strings used for record-keeping - shocked the team. Measuring across a whopping 1.4 billion light-years, Quipu consists of 68 galaxy clusters with a combined mass of about 2.4 × 10^17 solar masses. This behemoth of magnitude makes Quipu the largest superstructure ever accurately measured.
“This breaks the size record of all reliably measured cosmic structures,” confirmed the researchers.
J. Richard Gott III at Princeton University, who co-discovered the Sloan Great Wall, congratulated the team.
“The Quipu superstructure, end to end, is slightly longer than the Sloan Great Wall,” he said. “Congratulations to them for finding it.”
Scientists have long believed that, at large enough scales, matter should is evenly distributed throughout the universe. At smaller scales, superclusters as well as voids form. But the discovery of massive structures like Quipu challenges this idea.
Some experts argue that previous studies may have misinterpreted the universe’s large-scale distribution.
“Making observations in too small a part of the universe, which has been done earlier on, can be misleading,” said Böhringer.
Alexia Lopez at the University of Central Lancashire in the UK also pointed out that: “There is not yet one definition of the cosmological principle that every cosmologist agrees on.”
