Astronomers have detected the second most distant dusty, star-forming galaxy ever found in the universe - born 12.8 billion years ago.The findings showed that the galaxy was born in the first one billion years after the Big Bang.Being able to image an object born within the first billion years is remarkable, because the universe was too hot and too uniform to form anything for the first 400 million years, the researchers said."The Big Bang happened 13.7 billion years ago, and now we are seeing this galaxy from 12.8 billion years ago, so it was forming within the first billion years after the Big Bang," said Min Yun, astrophysicist at the University of Massachusetts at Amherst, in the US.
