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.

The luminosity distance D L is related to a factor called the "comoving transverse distance" D M by the equation D L = (1 + z) D M, where z is the redshift, and the comoving transverse distance is itself equal to the radial comoving distance (i.e., comoving distance between an object and ourselves) in a spatially flat universe.
In 1964 a quasar became the most distant object in the universe for the first time. Quasars would remain the most distant objects in the universe until 1997, when a pair of non-quasar galaxies would take the title (galaxies CL 1358+62 G1 & CL 1358+62 G2 lensed by galaxy cluster CL 1358+62 ).
But unlike the jet formed by J1601+3102, Porphyrion was found 7.5 billion light-years away from Earth in what’s called the “nearby” universe, rather than the early universe, according to the ...
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.

NASA's powerful Webb Telescope has spotted more than 40 ancient stars in a distant galaxy, researchers said in a new study. The study, published Monday in Nature, said the researchers used a ...
