SAN DIEGO-- A roll of photographic film 10 paces long marks the first step in a survey that will reach billions of light-years into space. The Sloan Digital Sky Survey's electronic camera, mounted on a 2.5-meter telescope in New Mexico, collected its first images of stars, galaxies, and quasars on the nights of 9 and 10 May (Science, 29 May, p. 1337). Converted into a photographic scroll, just 1% of the data from the first night drew gasps last week when five members of the team unrolled it during a press conference here at a meeting of the American Astronomical Society.
