Number 13 (Story #1), December 17, 1990 by Phillip F. Schewe and Ben Stein A DIGITAL SKY SURVEY , a 10-year, $14-million effort by the University of Chicago, Princeton University, and the Institute for Advanced Study, will map the location of 1 million galaxies and 100,000 quasars. The project, which may begin taking data in 1995, will use a special 2.5-m telescope (to be built in New Mexico) and record the spectra of 600 galaxies simultaneously. By comparison, the galaxy survey conducted by Harvard astronomers Margaret Geller and John Huchra, a survey which revealed the existence of colossal walls and voids of galaxies, mapped only thousands of galaxies, and did it by recording spectra one at a time.
