This is a list of the largest cosmic structures so far discovered. The unit of measurement used is the light-year (distance traveled by light in one Julian year; approximately 9.46 trillion kilometres). This list includes superclusters, galaxy filaments and large quasar groups (LQGs). The structures are listed based on their longest dimension.

Oct 28, 2024 · Astronomers have recently uncovered an enormous cosmic structure known as the "Big Ring" that challenges our fundamental understanding of the universe. This nearly perfect ring of galaxies, found over 6.9 billion light-years away, …

The Big Ring is composed of numerous galaxies and galaxy clusters that form a continuous, almost perfect ring-like pattern in space. With its diameter of 1.3 billion light years and a circumference of 4 billion light years , it is one of the largest known structures within the observable universe .

Jan 12, 2024 · Scientists at the University of Central Lancashire have discovered a gigantic, ring-shaped structure in space. It is 1.3bn light-years in diameter and appears to be roughly 15 …

Jan 22, 2024 · Cosmological theory suggests that the largest structures — in the form of chains of galaxies and galaxy clusters — that BAOs could form should be, at most, 1.2 billion light-years in length. Yet,...

In January 2024, Lopez revealed the discovery of another cosmic megastructure – a ring of distant galaxies with a diameter of 1.3 billion light years, which she has named the Big Ring.

The ring of GRBs lies at a distance of about 2.8 gigaparsecs (9.1 billion light years) from Earth at the redshift between 0.78 and 0.86 [2] and measures about 1.72 gigaparsecs (5.6 billion light years) in diameter, [2] making it one of the largest structures known. [3]

Jan 15, 2024 · The Big Ring spans an astounding 1.3 billion light years in diameter, a substantial fraction of the observable Universe's estimated 94 billion light years.

Jan 16, 2024 · Astronomers have discovered a second ultra-large cosmic structure, which challenges the existing theories of the universe. This massive ring-shaped object, the “Big Ring on the Sky,” is 9.2...

Dec 18, 2020 · GAL-CLUS-022058s is the largest and one of the most complete Einstein rings ever discovered in our universe. The object has been nicknamed by astronomers studying this Einstein ring as the "Molten Ring," which alludes to its appearance and host constellation.
