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".
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.

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.
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 ...
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 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 ...
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 ...
The spatial region from which we can receive light is called the observable universe. The proper distance (measured at a fixed time) between Earth and the edge of the observable universe is 46 billion light-years [50] [51] (14 billion parsecs), making the diameter of the observable universe about 93 billion light-years (28 billion parsecs).
