PASADENA, Calif. – Astronomers presented a new view of the "nearby" universe, probing the way that galaxies cluster together over distances of hundreds of millions of light years, at today’s meeting of the American Astronomical Society being held in Pasadena, Calif. The new map for the first time covers the whole sky, including the large portion ordinarily hidden by our own galaxy, the Milky Way, and reveals a complicated network of galaxies surrounding us. Galaxies do not uniformly dot the sky, explained University of Massachusetts astronomer Stephen Schneider, who headed up the project. Rather, gravitational forces spur them to form clusters and groups of clusters, called superclusters. The findings offer scientists clues about the conditions that existed during the early days of the universe.
