The Spectacular 3D maps of the universe have revealed inconceivable wall known as South Pole Wall.
The South Pole Wall rivals in size the Sloan Great Wall, the sixth largest cosmic structure discovered.
It stretches 1.4 billion light-years across that contains hundreds of thousands of galaxies.
It was remaining undetected until now because large parts of it sit half a billion light-years away behind the bright Milky Way galaxy and Zone of Avoidance.
Zone of Avoidance is the disc of our home galaxy, a region thick and bright with dust and gas and stars.
