Sloan Great Wall
The Sloan Great Wall is a gigantic wall of galaxies and, after the Hercules – Corona Borealis Great Wall and the extensive quasar cluster U1.27, is the largest known contiguous structure in the universe . It was determined using data from the Sloan Digital Sky Survey in Discovered in 2003. The structure is almost three times the size of the CfA2 Great Wall and is around 1.37 billion light years long . It is around a billion light years from Earth.
The Sloan Great Wall is a non- gravitationally bound arrangement of galaxies and is likely to collapse into multiple galaxy clusters in the future .
