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.

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 ...
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 ...
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).
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 ...
UDFy-38135539 (also known as "HUDF.YD3") is the Hubble Ultra Deep Field (UDF) identifier for a galaxy which was calculated as of October 2010 to have a light travel time of 13.1 billion years [2] with a present proper distance of around 30 billion light-years.
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.
Distant objects like this could help astronomers identify our solar system's missing planet. A newly discovered space object called 'Farfarout' is the most distant thing in our solar system Skip ...
