ASTRONOMY:
'First Light' for Giant Sky Survey
James Glanz
The Sloan Digital Sky Survey, an $80 million project involving researchers at seven universities and research institutions in the United States and a collaboration in Japan, has made its first images of the night sky. The survey, using a 2.5-meter telescope and an innovative electronic camera, will gather images of perhaps 200 million celestial objects and map the precise positions of a million galaxies in a 1.5-billion-light-year-wide chunk of the universe.
