The Giant Arc is a large-scale structure discovered in June 2021 that spans 3.3 billion light years. [1] The structure of galaxies exceeds the 1.2 billion light year threshold, challenging the cosmological principle that at large enough scales the universe is considered to be the same in every place (homogeneous) and in every direction ().
It was originally referred to as the Giant Arc, but later renamed to the Dragon Arc. [7] These arcs or deformations are mirages caused by gravitational lensing of distant galaxies by the massive galaxy cluster located between the observer and the magnified galaxies. [3] [8] This cluster shows an apparent magnitude of +22.
Consists of at least 15 clusters plus other interconnected filaments. It is the most massive galaxy supercluster discovered so far. [19] Big Ring (2024) 1,300,000,000 Made up of galaxy clusters. (Theoretical limit) 1,200,000,000 Structures larger than this size are incompatible with the cosmological principle according to all estimates. However ...
The Big Ring is a ring-shaped large-scale structure formed by galaxies and galaxy clusters near the constellation Boötes with a diameter of 1.3 billion light years, located 9.2 billion light years away. [1] It was discovered in 2024 by Alexia Lopez, a PhD student at the University of Central Lancashire. [2]
In June 2021, the Giant Arc was discovered, a structure spanning approximately 1000 Mpc. [24] It is located 2820 Mpc away and consists of galaxies, galactic clusters, gas, and dust. In January 2024, the Big Ring was discovered. It is located 9.2 billion light years away from Earth has a diameter of 1.3 billion light years or around the size of ...
Listed below are galaxies with diameters greater than 700,000 light-years. This list uses the mean cosmological parameters of the Lambda-CDM model based on results from the 2015 Planck collaboration, where H 0 = 67.74 km/s/Mpc, Ω Λ = 0.6911, and Ω m = 0.3089. [3]

The western arm is less strong, but it is considerably longer, as its outermost parts form an arc with H II regions, wrapping nearly 360 degrees around the disk and forming a pseudoring. NGC 6907 also has a tidal tail with low surface brightness. The asymmetric tail extends from the north part of the disk of the galaxy towards the west and ...
