Scientists have discovered a celestial structure made of galaxies more than 1.4 billion light-years long and 600 million deep in the skies over the South Pole that until recently had never been seen, according to a report.

The South Pole Wall, as it has been dubbed, is situated along the southern border of the universe from the perspective of Earth, and consists of thousands of galaxies, hydrogen gas, dust and dark matter according to Vice and MIT Technology Review. It's also one of the largest known structures in the universe.

The wall is among a number of structures that make up the cosmic web, including the Great Wall, the Bootes Void, the comparably-sized Sloan Great Wall and the Hercules Corona-Borealis Great Wall, the largest known structure at 10 billion light-years wide, according to MIT.

That’s about a tenth of the diameter of the observable universe, Vice reported.:snip:
