Raffaello writes: CNN reports: Edo Berger got an alert early last Thursday morning when a satellite detected a 10-second blast of energy known as a gamma ray burst coming from outer space. Telescopes around the world swiveled to focus on the explosion, soon picking up infrared radiation, which travels more slowly than gamma rays. Berger waited for the visible light which he expected to come next. It never arrived. "We were kind of blown away. We immediately knew what that meant," Berger said. What it meant was that he was looking at the oldest thing ever spotted — an enormous star exploding 13 billion years ago.
