+ - Distant Stellar Explosion Helps Map Universe's Dark Ages->

Submitted by sciencehabit
sciencehabit (1205606) writes "Near the beginning, the universe was without form and void, and darkness was upon the face of the deep. That's because until about a billion years after the big bang, there were no galaxies or stars to illuminate the heavens, which were then filled primarily with neutral hydrogen gas. But a rare ultra–high-energy stellar explosion called a gamma ray burst has offered a new glimpse into this obscure period—the so-called cosmic dark ages—and may help nail down precisely when it ended. A new study of the explosion's afterglow suggests that such neutral hydrogen abounded a billion years after the big bang, so the dark ages weren’t quite over then."
