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.

His consciousness floats out of his body, away from Earth, beyond our galaxy. Before the man is brought back to life, he sees our entire universe as a speck in an immense hand. [6] Sterling was an avid reader of Edgar Allan Poe's writings, so Poe's last book Eureka: A Prose Poem may have influenced "The Testimony of the Suns."
One particularly distant body is 90377 Sedna, which was discovered in November 2003.It has an extremely eccentric orbit that takes it to an aphelion of 937 AU. [2] It takes over 10,000 years to orbit, and during the next 50 years it will slowly move closer to the Sun as it comes to perihelion at a distance of 76 AU from the Sun. [3] Sedna is the largest known sednoid, a class of objects that ...
The spacecraft, still traveling at 64,000 km/h (40,000 mph), is the most distant human-made object from Earth and the first to leave the Solar System. [6] Its mission has been extended and continues to this day, with the aim of investigating the boundaries of the Solar System , including the Kuiper belt , the heliosphere and interstellar space .
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 ).

The faint object has a visual magnitude of 24.64, comparable to the visual magnitudes of Pluto's smaller moons. [ 9 ] [ 19 ] It was initially estimated to be 300 km (190 mi) in diameter under the assumption of an albedo of 0.15, [ 5 ] though observations of a single-chord stellar occultation at Penticton, Canada on 20 October 2018 suggested a ...
