Astronomers have detected the most distant explosion ever witnessed in the heavens. It was a flash so powerful that they could observe the faint light as it came in from almost the edge of the known universe. The discovery of this burst opens a new view into the frontiers of space.
The U.S. space agency's Swift satellite was routinely scouring the cosmos for exploding stars on September 4 when it spotted what scientists have since realized is the most distant such burst on record.
In astronomy, distance means time. The further something is away, the longer its light has been traveling to get to us. So the star blast is also the most ancient ever observed.
