Record gamma ray burst: GRB 080319B
On Wednesday morning, at 7:12 am Central European Time, NASA observed a gamma ray burst whose after glow you could see with your naked eye for 30 seconds. The star used to have 40 solar masses and its distance was 7.5 billion light years, more than 1/2 of the visible Universe away from us. It was by far the most distance GRB ever seen. The previous record distance was 2.5 billion light years.
