The Hercules-Corona Borealis Great Wall (HCBGW) Supercluster Complex is the largest structure or the largest single entity or the largest object ever discovered in the universe.
The Hercules-Corona Borealis Great Wall (HCBGW) Supercluster Complex has a size of approximately 10 billion light-years in length and an estimated mass of about 40,000 to 80,000 times that of the Milky Way galaxy.
It has at least 1000 visible galaxies and many more that are not visible (dark galaxies). Its estimated distance from Earth is about 10 billion light-years.
Discovery of the Hercules-Corona Borealis Great Wall (HCBGW) Supercluster Complex:
In early November 2013, a team of American and Hungarian astronomers led by István Horváth, Jon Hakkila, and Zsolt Bagoly made a groundbreaking discovery of HCBGW while analyzing data from the Swift Gamma-Ray Burst Mission.
The Swift mission is dedicated to studying gamma-ray bursts (GRBs), the most powerful explosions in the universe. However, the team’s analysis went beyond just GRBs. They combined data from Swift with observations from ground-based telescopes, creating a more comprehensive picture of the cosmos.
The Power of Collaboration: It was through this meticulous analysis of combined datasets that the team stumbled upon the telltale signs of the HCBGW. By studying the distribution of GRBs alongside other celestial objects, they identified a colossal filament stretching an astounding 10 billion light-years across.
This discovery marked a significant leap in our understanding of large-scale structures in the universe.
The Name’s Hercules-Corona Borealis Great Wall (HCGBT):
The name Hercules-Corona Borealis Great Wall is a tribute to the collaborative effort that led to its discovery. Here’s a breakdown of the name:
Hercules: This portion references the Hercules constellation, a prominent feature in the night sky near the location of the wall.
Corona Borealis: The Northern Crown constellation also plays a role in pinpointing the wall’s position.
Great Wall: This aptly describes the structure’s immense size and filament-like shape.
The combined name, Hercules-Corona Borealis Great Wall (HCGBT), acknowledges both the specific celestial location and the wall’s grand scale.
Size of the Hercules-Corona Borealis Great Wall (HCBGW) Supercluster Complex:
The sheer size of the HCBGW is difficult to grasp, measuring approximately 10 billion light-years in length, This is roughly one-ninth (10.7%) of the diameter of the observable universe (93 billion light-years in diameter). However, the clustering encompasses 19 to 22 GRBs and is three times longer than the remaining 14 GRBs.
The grouping spans 20 constellations and encompasses 125 degrees of the sky, or almost 15,000 square degrees in total, equivalent to around 18 to 23 billion light-years in length. It is at redshifts 1.6 to 2.1. It dwarfs previous contenders for the “largest structure” title.
Imagine a celestial serpent stretching across a significant portion of the observable universe, that’s the scale of the HCBGW. Even the Laniakea Supercluster, which encompasses our Milky Way galaxy, seems insignificant next to the HCBGW’s colossal scale.
Mass of the Hercules-Corona Borealis Great Wall (HCBGW) Supercluster Complex:
The mass of the HCBGW is equally staggering. Estimates suggest it contains roughly 40,000 to 80,000 times more mass than our Milky Way galaxy. Imagine a cosmic leviathan woven from hundreds of billions of stars, dust, gas, and dark matter, that’s the essence of the HCBGW.
Immensity of the Hercules-Corona Borealis Great Wall (HCBGW) Supercluster Complex:
This immensity offers valuable insights into the universe’s formation and evolution. The presence of such a large-scale structure hints at the influence of gravity in shaping the cosmos after the Big Bang.
Studying the HCBGW allows scientists to piece together the cosmic web, a vast network of filaments and voids that defines the large-scale structure of the universe.
Hercules-Corona Borealis Great Wall (HCBGW)’s Distance from Earth:
Hercules-Corona Borealis Great Wall (HCBGW) is about 10 billion light-years away from Earth in the constellations of Hercules, Corona Borealis, Lyra, Boötes, and Draco.
Structure of the Hercules-Corona Borealis Great Wall (HCBGW) Supercluster Complex:
The HCBGW isn’t a monolithic structure. It’s a complex tapestry of interwoven superclusters, each containing hundreds of individual galaxies. These galaxies, like our Milky Way, are vast collections of stars, gas, and dust.
Within the HCBGW, estimates suggest there are at least tens of thousands of visible galaxies, with countless others shrouded in the invisible cloak of dark matter.
Dark matter, a mysterious substance that doesn’t interact with light but exerts a gravitational pull, is thought to be the dominant component of the HCBGW. In fact, visible matter like stars and gas is estimated to constitute only a small fraction of the wall’s total mass.
Understanding the distribution of dark matter within the HCBGW could shed light on its formation and evolution.
The galaxies within the HCBGW aren’t static. They are bound by gravity, swirling and interacting with each other in a cosmic dance. Studying these interactions can tell us about galaxy formation and evolution within large-scale structures like the HCBGW.
What is Cosmic Web?
The cosmic web is a large-scale structure that permeates the entire observable universe. Imagine a vast network of filaments, like threads, stretching across space, interconnected with vast, empty regions called voids. These filaments are composed of superclusters, clusters, and individual galaxies, all bound together by the invisible hand of gravity.
The HCBGW, with its immense size and collection of superclusters, is a prominent filament within this cosmic web. It plays a significant role in shaping our understanding of this large-scale structure:
Visualizing the Web: The HCBGW serves as a prominent landmark within the cosmic web. Studying its location and structure helps us map the distribution of matter in the universe and visualize the intricate connections within the web.

What is a Super Cluster Complex?
A supercluster complex is an incredibly large grouping of Superclusters. A supercluster is a massive collection of smaller galaxy clusters or galactic groups, it is one of the biggest known formations in the universe. Imagine a massive cluster of galaxies, containing hundreds or even thousands of individual galaxies, all interconnected by gravity.
They can span hundreds of millions of light-years, dwarfing even the most impressive clusters. The HCBGW, for example, is an amazing example, consisting of multiple superclusters woven together.
