A gamma ray burst may be most distant object from Earth ever observed. The object is so far that it is giving scientists a glimmer into the early universe.
GRB 090429B (the numbered name denotes its April 29, 2009, discovery) is estimated to be some 13.14 billion light years away from Earth. Given that the universe is only estimated to be about 13.7 billion years old, that makes the source of this light really young in a cosmic sense, originating when the universe was just 4 percent of its current age and 10 percent of its present size. It’s also way, way out there, further than any confirmed quasar or galaxy on the books.
