Scientists have discovered the largest structure yet found in the universe, a “Great Wall” of galaxies 1.37 billion light-years long, according to an article in Science, Oct. 24, 2003.

This cosmic ribbon dwarfs anything seen before by more than 600 million light-years. The wall’s vastness pushes the limits of existing cosmological theories.
