THE SURVEY OF GALAXY REDSHIFTS published by Harvard-Smithsonian astronomers (Margaret Geller, 617-495-7409) a decade ago, a survey which revealed that the universe is filled with immense sheets and clumps of galaxies, as well as regions nearly devoid of galaxies, has now been extended to cover parts of the southern celestial hemisphere. The new survey, supplementing northern observations at the Whipple Observatory in Arizona with southern- hemisphere observations in Chile, Argentina, and South Africa, shows that southern skies are also clumpy on a scale of 100 million light years.
