Scientists have discovered a celestial structure made of galaxies more than 1.4 billion light-years long and 600 million deep in the skies above the South Pole that have never been seen until recently, according to a report.
The South Pole wall, as it has been called, is located along the southern edge of the universe from Earth’s perspective, and consists of thousands of galaxies, hydrogen gas, dust, and dark matter according to Vice and MIT Technology Review. . It is also one of the largest known structures in the universe.
The wall is among a series of structures that make up the cosmic network, including the Great Wall, the Void of the Void, the Sloan Great Wall of comparable size, and the Great Wall Hercules Corona-Borealis, the largest known structure in 10 billion light years. wide, according to MIT.
That’s about a tenth the diameter of the observable universe, Vice reported.

The findings were first reported last Friday in the Astrophysical Journal.
The South Pole wall, however, is half the distance from Earth to the Great Wall Hercules Corona-Boreal – 500 million light years – astronomically close and was hidden by the glow of the Milky Way in an area called Avoidance Zone, according to MIT
It was discovered when scientists saw galaxies in different directions around it affected by its gravitational pull.
The wall is the largest structure discovered within a 650 million light-year radius of Earth, Pomarède said, according to Vice.
“When our visualizations indicated that something was happening at the celestial South Pole, we were surprised,” Daniel Pomarède cosmographer at the Paris-Saclay University in France told Vice in an email. “In fact, there were no reports of a large-scale structure in this region.”

Pomarède told Vice that the arc-shaped makeup on the wall is the reason its “length can fit the observed sphere,” adding that the map the scientists used “fades just beyond the wall. ” “So maybe we are not seeing everything, if it turns out that it is moving away from us beyond our observation limit.”
