Marcus. -> Star Explodes Halfway Across Universe (3/22/2008 10:09:55 AM)

Astronomers are familiar with seeing amazing things through their telescopes. But nothing prepared them for an incredible explosion detected early Wednesday morning by NASA’s Swift satellite. At 2:12 a.m. EDT, Swift detected an explosion from deep space that was so powerful that its afterglow was briefly visible to the naked eye. Even more astonishing, the explosion itself took place halfway across the visible universe! Never before has anything so far away come even close to naked-eye visibility. The explosion was so far away that it took its light 7,500,000,000 (7.5 billion) years to reach Earth! In fact, the explosion took place so long ago that Earth had not yet come into existence. NASA
