Violent Explosion Is Most Distant Object Ever Seen

• Space
Light from a star that exploded 13 billion years ago has been detected, becoming the most distant object in the universe ever observed.

The light from the distant explosion, called a gamma-ray burst, first reached Earth on April 23 and was detected by NASA's Swift satellite. Gamma-ray bursts are thought to be associated with the formation of star-sized black holes as massive stars collapse.

Within hours, telescopes around the world were turned on the burst — the most violent explosions in the universe — observing its fading afterglow to glean clues about its source and location.
