Light from huge explosion 12 billion years ago reaches Earth

more »

Intense light from the enormous explosion of a star 12.1 billion years ago -- shortly after the Big Bang -- recently reached Earth and was observed by a robotic telescope. Known as a gamma-ray burst, these rare, high-energy explosions are the catastrophic collapse of a star at the end of its life. Astronomers can analyze the observational data to draw further conclusions about the structure of the early universe.
