In general, the farther away a cosmic object is from us on Earth, the more redshifted its light will be. > > "Additionally, the team looked at GN-z11’s emission lines—observable, chemical signatures in the light coming from cosmic objects." > > Comment: At 13.4 billion years old it was born just .38 billion years after the Big Bang. A short while before the Milky Way when thinking in billions
