This image shows the position of the most distant galaxy discovered so far within a deep sky Hubble Space Telescope survey called GOODS North. The survey field contains tens of thousands of galaxies stretching far back into time. The remote galaxy GN-z11, shown in the inset, existed only 400 million years after the Big Bang when the universe was only 3 percent of its current age. ...
