Death Star Video |
Solve the Most Powerful Mystery In the Universe |
So bright, they are a billion times more luminous than the sun; so distant, their light takes billions of years just to reach Earth, the elusive death stars puzzled astronomers for nearly three decades before an international alliance finally unlocked their secrets. The celestial phenomena of death stars is characterized by amazingly violent explosions that may even have the power to eradicate life in an entire galaxy. First detected in 1967, these intense outer-space gamma ray bursts were not understood until recently. With this video, you join NOVA and venture into deep space to explore some of the most energetic events ever glimpsed. See how these celestial phenomena can teach us about the dawn of the universe and hear a controversial theory of how a gamma ray burst somewhere in our own galaxy could destroy life on Earth. Close-captioned. Duration: 60 minutes.
