These were the most remote objects discovered at the time. The pair of galaxies were found lensed by galaxy cluster CL1358+62 (z = 0.33). This was the first time since 1964 that something other than a quasar held the record for being the most distant object in the universe.

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, [7] 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 Lambda-CDM model is a cosmological model that explains the formation of the universe after the Big Bang. It is a relatively simple model that predicts many properties observed in the universe, including the relative frequency of different galaxy types; however, it underestimates the number of thin disk galaxies in the universe.

Nasa’s James Webb Space Telescope has found the two most distant galaxies ever seen, the space agency has said. The two galaxies are the earliest ever seen in the universe, dating back to when ...
Scientists have spotted mysterious, incredibly bright objects in the distant universe. ... insanely rapid formation at the beginning of time. This is, without a doubt, the most peculiar and ...
[1] [2] This redshift made it the most distant, and therefore earliest known quasar in the observable universe as of 2023. [ 3 ] [ 4 ] To detect this object, astronomers working at the Chandra X-ray Observatory used the Abell 2744 's cluster mass as a gravitational lens in order to magnify distant objects directly behind it.

Astronomers used the James Webb Space Telescope to spot a Milky Way-like galaxy that formed soon after the big bang created the universe.
GRB 090423 was a gamma-ray burst (GRB) detected by the Swift Gamma-Ray Burst Mission on April 23, 2009, at 07:55:19 UTC whose afterglow was detected in the infrared and enabled astronomers to determine that its redshift is z = 8.2, making it one of the most distant objects detected at that time with a spectroscopic redshift (GN-z11, discovered ...
