Far-Out Cosmic Walls
New findings suggest that galaxies form massive wall-like structures in the far reaches of the universe. In the 1 November issue of the Astrophysical Journal, Judith Cohen of the California Institute of Technology and colleagues at the University of Hawaii report evidence for what may be walls of galaxies as far as 8 billion light-years away, indicating that matter formed distinct structures earlier in the universe's history than many scientists expected.
