Hercules–Corona Borealis Great Wall

The Hercules–Corona Borealis Great Wall is the largest known structure in the Universe, which is about 10.5 billion light-years away from Earth. Astronomers study this giant wall of galaxies held together by the force of gravity closely, mapping gamma-ray bursts coming from it. The Hercules–Corona Borealis Great Wall is about 10 billion light-years long and 7.2 billion light-years wide. In fact, it is wider than the Milky Way, which is about 100,000 light-years wide.

Giant GRB Ring

Discovered in 2015, this giant galactic ring consisting of 9 gamma-ray bursts, has the most energy of any wave in the electromagnetic spectrum. This unique structure is 5.6 billion light years in diameter and lies at a distance of about 9.1 billion light-years from Earth.

Huge Large Quasar Group

This large quasar group was discovered in 2013. Quasars are highly luminous objects releasing large amounts of energy. The structure of 73 quasars is within the vicinity of the constellation Leo and measures about 4 billion light-years across. The Huge Large Quasar Group is an object of close attention of scientists.

Maggie

This vast cloud of hydrogen gas within the Milky Way galaxy was discovered in 2021. The 3,900 light-years long structure was named "Maggie," which is short for the Magdalena River, the longest river in Colombia. This massive hydrogen filament lies 55,000 light-years from Earth. Maggie is five times the size of the largest gas clouds ever discovered by astronomers.

South Pole Wall

The South Pole Wall is a colossus, consisting of a giant wall of galaxies that extends across at least 1.37 billion light-years of space. The structure lies between the constellations Cetus and Apus. The South Pole Wall is located near the Milky Way and spans 500 million light-years away from Earth. The object was discovered in 2020.
