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.

A finite universe is a bounded metric space, where there is some distance d such that all points are within distance d of each other. The smallest such d is called the diameter of the universe, in which case the universe has a well-defined "volume" or "scale".
In this map of the Observable Universe, objects appear enlarged to show their shape. From left to right celestial bodies are arranged according to their proximity to the Earth. This horizontal (distance to Earth) scale is logarithmic.
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 ).
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 ...
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 ...
In astronomy, the terms object and body are often used interchangeably. However, an astronomical body or celestial body is a single, tightly bound, contiguous entity, while an astronomical or celestial object is a complex, less cohesively bound structure, which may consist of multiple bodies or even other objects with substructures.
Astronomers used the James Webb Space Telescope to spot a Milky Way-like galaxy that formed soon after the big bang created the universe.
