Great Wall of Sloan

Sloan Great Wall is a complex of superclusters of galaxies that extends over a billion light-years . It is a flat structure of galaxies and voids , the third largest known similar structure in the Universe (it was the first before the discovery of the Great Wall of Hercules - Northern Corona in 2013).

In length, the "wall" extends to 1.37 billion light years . It is located approximately 1.2 billion light-years from Earth .

The Great Wall of Sloan is 2.74 times the Great Wall of CfA2 , the previous record holder in length. With a radius of 1.38 billion St. l (1.3⋅10 ²⁵ m, or 13 Im), which is approximately 1/60 of the diameter of the observed Universe . Located in the densest region of the structures of the Universe, it is followed by the Virgo Supercluster - Veronica's Hair (SCL 111).

The opening of the Great Wall of Sloan was announced on October 20, 2003 by scientists J. Richard Gott and Mario Yurich of Princeton University . This discovery was made thanks to the Sloan Digital Sky Survey (SDSS).
