The object's name is derived from its location in the GOODS-North field of galaxies and its high cosmological redshift number (GN + z11). Up until the discovery of JADES-GS-z13-0 in 2022 by the James Webb Space Telescope, GN-z11 was the oldest and most distant known galaxy yet identified in the observable universe, having a spectroscopic redshift of z = 10.957, which corresponds to a proper distance of approximately 32 billion light-years (9.8 billion parsecs). The 2015 discovery was published in a 2016 paper headed by Pascal Oesch and Gabriel Brammer (Cosmic Dawn Center). It was among the farthest known galaxies from Earth ever discovered. GN-z11 is a high-redshift galaxy found in the constellation Ursa Major.
