A gamma ray burst designated GRB090423 was detected by the NASA Swift satellite last Thursday, April 23, may have occurred when the universe was only 630 million years old. This may be one of the earliest explosions of a massive star. For more info see http://www.cfa.harvard.edu/news/2009/pr200911.html
