A cosmic explosion of gamma-rays from near the edge of the known universe - announced today by NASA - is only the latest piece in 30-year scientific puzzle. Explore the trail of discovery that has led scientists to learn that these daily events each release more energy in 10 seconds than the Sun will emit in its entire 10-billion year lifetime.
