Light that has traveled for over 13.4 billion years to reach our neighborhood of space has been confirmed as originating from the earliest, most distant galaxy detected yet.
That places the most distant of these four very young objects at the very dawn of the Universe, just a short time after the Big Bang – a time period when the Universe was still foggy and bleary and the first rays of light were penetrating the darkness.
So detailed are the JWST’s long spectroscopic observations that researchers can not only measure the distance the light of these galaxies has traveled, they can also infer some of the galaxies’ properties.
