Welcome to the companion Web site to "Death Star," originally broadcast on January 8, 2002. The program probes the deep mysteries of gamma-ray bursts, the most powerful celestial explosions since the big bang. Here's what you'll find online:
  • One Astronomer's Universe
    What's it like to think cosmological thoughts all day? How does one get one's mind around such concepts as black holes or billions of light-years?

  • A Bad Day in the Milky Way
    Astrophysicist Jerry Bonnell of NASA's Goddard Space Flight Center describes what could happen to our planet if a gamma-ray burst occurred nearby in our own galaxy. You don't want to know.
