Light emitted by galaxy 13.1 bn years in the past detected
California-based astronomers have spotted a galaxy about 13.1 billion light-years away, so far away that light from its stars takes 13.1 billion years to reach the Earth in the 13.8 billion-year-old universe. The distant galaxy in the past was found using gravitational lensing, a phenomenon when giant galaxy clusters bend light's path by gravity, magnifying images of objects behind it.
