A gamma-ray burst known as GRB 090429B is the current candidate for the most distant object in the universe. NASA’s Swift satellite detected it in April 2009. It lies an estimated distance of 13.14 billion light years away – more distant than any other known quasar and possibly more distant than any previously known galaxy or gamma-ray burst..
This particular gamma ray burst is thought to have erupted from a supernova, or exploding star, when the universe was less than 4% of its present age – around 520 million years old – and less than 10% of its present size. Derek Fox, associate professor of astronomy and astrophysics at Penn State and a co-author of the paper, said:
