Astronomers have used the Subaru and Keck telescopes to discover gigantic filaments of galaxies stretching across 200 million light-years in space. These filaments, formed just 2 billion years after the Big Bang, are the largest structures ever discovered in the Universe. The filaments contain at least 30 huge concentrations of gas, each of which contains 10x the mass of the Milky Way.
