    • Abstract:
      The article discusses gamma ray bursts and how astronomers may be able to use them to probe the early universe. Gamma-ray bursts are the universe's most luminous events. Astronomers are interested in the long-duration bursts, which signal the death of a massive star that existed within a billion years of the big bang. These bursts allow astronomers to chart the universe to further distances.
