'''GN-z11''' adalah [[galaksi]] tinggi pergeseran merah ditemukan di [[konstelasi]] [[Ursa Mayor|Ursa Major]], dan saat ini merupakan galaksi yang tertua dan paling jauh yang dikenal di alam semesta yang dikenal. GN-Z11 memiliki pergeseran merah spektroskopi dari z = 11,1, yang sesuai dengan [[jarak]] comoving sekitar 32 miliar tahun cahaya dari Bumi. GN-Z11 diamati karena ada 13,4 miliar tahun yang lalu, hanya 400 juta tahun setelah Big Bang. jaraknya karena itu secara luas dilaporkan sebagai 13,4 miliar tahun cahaya.<ref name=":3">{{Templat:Cite web|url=http://phenomena.nationalgeographic.com/2016/03/03/astronomers-spot-most-distant-galaxy-yet-at-least-for-now/|title=Astronomers Spot Most Distant Galaxy—At Least For Now|website=Phenomena|access-date=March 4, 2016|quote=Yep, it took 13.4 billion years for light from the galaxy to zoom through the universe and collide with the Hubble Space Telescope.
