Astronomers: Unprecedented gamma ray burst may signal star's black hole death

• Terrence Aym
Now NASA has detected an incredible cosmic blast in the center of a far distant galaxy located more than 3.8 billion light years away from Earth. A light year is the distance that light, traveling at 186,000 miles per second, travels in one year: nearly six trillion miles. The gigantic blast is incredibly intense and has lasted much longer than any ever recorded. The cosmic detonation has sent shock waves tearing through the universe. The raw, frightening destructive power of the event has catapulted huge streams of X- and gamma rays—spreading a deadly swath of roiling destruction—through entire regions of deep space.
