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 ).
Astronomers have spied a monster radio jet in the distant universe that’s twice the width of the Milky Way galaxy. The ancient object formed when the universe was less than 10% of its current ...
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 cosmic distance ladder (also known as the extragalactic distance scale) is the succession of methods by which astronomers determine the distances to celestial objects. A direct distance measurement of an astronomical object is possible only for those objects that are "close enough" (within about a thousand parsecs) to Earth. The techniques ...
Ceers-2112 formed soon after the big bang created the universe (which is estimated to be 13.8 billion years old), and the galaxy’s distinct structure was already in place 2.1 billion years later.
NGC 1262 is a barred spiral galaxy [3] located in the constellation Eridanus. [4] NGC 1262 is about 686 million light-years [5] from Earth.This galaxy was formerly believed to be the most distant object in the New General Catalogue, [6] however, in 2023 using data from Ann Isaacs from the University of Minnesota, Stephen Odewahn from the McDonald Observatory used new radial velocity ...
