Light's Debut: Good Morning, Starshine!

7:01pm, August 7, 2001

Astronomers have for the first time detected signs of one of the earliest and least understood eras in the universe, the murky time just before the first stars and quasars flooded the cosmos with light.

The new observations, announced independently by two teams, "are very important because they are beginning to probe the time [just after] the first massive stars and quasars came into being," comments theorist David N. Spergel of Princeton University.

The findings reveal that these objects first illuminated the universe about 900 million years after the Big Bang, says codiscoverer Robert H. Becker of University of California, Davis and the Lawrence Livermore (Calif.) National Laboratory.
