Summary

CHICAGO-- In its first few days of scanning the heavens, the Sloan Digital Sky Survey's 2.5-meter telescope has bagged three of the four most distant quasars ever seen, including a new record-holder. It also found another nine of these distant beacons at distances nearly as great. Researchers hope to use the thousands of quasars expected from the Sloan as markers of cosmic structure in the early universe and probes of the gases wafting through space over billions of light-years.
