Over the past decade, an international team of astronomers, led in part by Brent Tully of the Institute of Astronomy at the University of Hawaii, has been mapping the distribution of galaxies around the Milky Way. They discovered a huge structure outside Lanyakei – superclusters of galaxies, including our own. Astronomers have named the recently identified structure of the South Pole Wall. A study of scientists was published in the Astrophysical Journal.
On three-dimensional maps of the universe, scientists have discovered one of the largest cosmic structures ever found. The wall of unbelievable size extends for 1.4 billion light-years in length and contains hundreds of thousands of galaxies. The wall of the South Pole is located immediately after the supercluster of Lanikei, encircling this region.
The densest part lies in the direction of the South Pole of the Earth, which inspired astronomers to name the structure.
The wall of the South Pole is as great as the Great Wall of Sloan. This is one of the largest structures known in the universe. One light-year is approximately 9 trillion km, so such space structures are incredibly huge. But the new discovery is much closer.
The University of Paris space cartographer, Daniel Pomare, one of the leading authors of the study, explained how such a large and not so distant structure went unnoticed. This is due to its location in the sky, which has not been fully examined. Also, direct observations of this part of the cosmos are hindered by areas of galactic dust and clouds in the foreground. Scientists have discovered the South Pole Wall due to its gravitational effect captured at the speeds of a sample of galaxies.
