Summary

This spring, astronomers detected GRB 090423, the most distant gamma ray burst they had ever seen. Its redshift of 8.2 shows that it went off a mere 625 million years after the big bang, proving that the universe had already come alive with stars when it was less than 5% of its present age. GRB 090423's discovery and the ensuing race to publish observations offer a glimpse into 21st century astronomy—a high-stakes pursuit in which communications networks make possible worldwide, round-the-clock collaborations, and pressures for cooperation and competition often come into simultaneous play.
