came across this today. thought i'd put it in this thread since its related
so if it took 13 billion light years for us to see this event, then the universe is at least 13 billion years old + age of this dead star
Scientists at the Gemini Observatory in Hilo, Hawaii, say they have spotted a gamma-ray burst that is about 13 billion light-years, or 76,400,000,000,000,000,000,000 miles, away from Earth. The scientists are calling it the most distant object ever seen in the universe. While NASA scientists say the discovery is certainly significant, because other astronomers have similar claims, they say it is the most distant stellar explosion spotted in the universe. The gamma-ray burst, called GRB 090423, is from a star that died when the universe was only 630 million years old, or less than 5 percent of its present age, according to NASA. The fading infrared afterglow of the burst appears in the center of this false-color image taken with the Gemini North Telescope in Hawaii.
