NASA Satellite Detects Naked-Eye Explosion Halfway Across Universe

Gamma-Ray Bursts (GRBs) are thought to occur when a star runs out of fuel, and explodes.
On 19 March 2008, 2 days ago, NASA recorded a GRB that was 2.5 million times more luminous than the most luminous supernova ever recorded, making it the most intrinsically bright object ever observed by humans in the universe!
Measurements estimate this supernova happened about 7.5 billion years ago, which means it happened even before the solar system was born, and when the universe was less than half the age it is now.
