GN-z11
Sign in to saveGN-z11 is a high-redshift galaxy discovered by NASA's Hubble Space Telescope in the constellation Ursa Major. It is among the farthest galaxies from Earth ever found. The 2015 discovery was published in a 2016 paper headed by Pascal Oesch and Gabriel Brammer (Cosmic Dawn Center). 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 galaxy yet identified in the observable universe, having a spectroscopic redshift of , which corresponds to a proper distance of approximately . Data published in 2024 established that the galaxy

GN-z11 is a high-redshift galaxy discovered by NASA's Hubble Space Telescope in the constellation Ursa Major. It is among the farthest galaxies from Earth ever found. The 2015 discovery was published in a 2016 paper headed by Pascal Oesch and Gabriel Brammer (Cosmic Dawn Center). 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 galaxy yet identified in the observable universe, having a spectroscopic redshift of , which corresponds to a proper distance of approximately . Data published in 2024 established that the galaxy contains the most distant, and therefore earliest, black hole known in the universe, estimated at around 1.6 million solar masses.
The object's name is derived from its location in the GOODS-North field of galaxies and its high cosmological redshift number . It is observed as it existed 13.4 billion years ago, just 400 million years after the Big Bang; as a result, its distance is sometimes inappropriately reported without qualification as 13.4 billion light-years, its light-travel distance measurement.
