The Grus Wall is a superstructure of galaxies ("wall of galaxies") formed in the early universe,[1][2] named for the Grus constellation in which it is found ("grus" is Latin for "crane").[3] It has an average redshift of z=2.38 and lies about 10.8 billion light-years away. The Wall is around 300 million light-years long, comparable in size to the Sloan Great Wall.[3] The Wall is "perpendicular" to the Fornax Wall and Sculptor Wall.[4][5]
The Grus Wall was discovered in 2003 by Povilas Palunas, Paul Francis, Harry Teplitz, Gerard Williger, and Bruce E. Woodgate through the use of wide-field telescopes.[3]
