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.

GRB 090423 is a gamma ray burst, which previously held the record for most distant object, and remains the most distant object with a spectroscopic redshift. The methods used to determine the distances to very distant cosmic objects are described in the "Cosmic distance ladder".
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 ...
Given the distance between Earth and the objects from the early days of the universe, when telescopes like Webb observe light from the distant cosmos, it’s effectively like looking into the past.
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 flashes of radio energy emanate from distant galaxies, with the most distant and most powerful ever observed being found 8 billion light-years away and documented in a 2023 study. While many ...

Researchers spotted three of the mysterious objects. Their light came to us from when the universe was only 600-800 million years old, about 5 per cent of its current age.
