Number 115 (Story #1), February 25, 1993 by Phillip F. Schewe and Ben Stein THE HARVARD-SMITHSONIAN REDSHIFT SURVEY , which measures the Doppler shift of spectra from galaxies out to a distance of about 500 million light years from Earth, has been expanded. The earlier survey, featuring numerous voids and clumps of galaxies, including a manlike stick-figure pattern of galaxies, covered a slice of sky 6 degrees thick and 135 degrees around. The newer survey again shows large congregations of galaxies (but none larger than the "Great Wall" of galaxies previously reported) for an enlarged annular volume 36 degrees thick and 360 degrees around. By 1995, the Harvard astronomers---Margaret Geller, John Huchra, and Ron Marzke---expect to have a complete survey of northern-hemisphere galaxies brighter than 15th magnitude.
