The spectacular 3D map of the universe reveals one of the largest universe structures ever, with almost incredible walls spanning 1.4 billion light years, Across hundreds of thousands of galaxies.

What is called the “Antarctic Wall” has been hidden and invisible, and it has not been discovered until now, because most of it is located 5 billion light years from the bright Milky Way galaxy Far away. The Antarctic Wall is comparable in size to the Sloan Great Wall, which is the sixth largest cosmic structure discovered. (A light year is about 6 trillion miles, or 9 trillion kilometers, so this”largest cosmic structure” is incredible).

Astronomers have long noticed that galaxies are not scattered randomly throughout the universe, but gathered in the so-called universe In the net, galaxies in huge hydrogen beams are strung like pearls on necklaces, surrounding huge and empty voids.

Cosmologist and researcher Daniel Pomarede of the University of Saclays in Paris, France told Live Science that drawing these interstellar lines belongs to the field of cosmology, which is”cartography of the universe” .

Previous cosmological work has mapped the scope of other galactic collections, such as the current structural record holder, Hercules-Corona Arctic Great Wall, which spans 10 billion light years, or is visible in the universe More than one tenth.

In 2014, Pomarede and colleagues launched the Laniakea super cluster, which is the Milky Way where our own galaxy is located. The width of Lanaiikea (Lanaikea) is 520 million light years, including about 100 million Suns.
