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 ...
Antoine Lavoisier publishes Traité Élémentaire de Chimie, the first modern chemistry textbook. It is a complete survey of (at that time) modern chemistry, including the first concise definition of the law of conservation of mass, and thus also represents the founding of the discipline of stoichiometry or quantitative chemical analysis.

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 ...
This galaxy is the most distant object in the Messier Catalog, followed by M91. M109 has three satellite galaxies ( UGC 6923 , UGC 6940 and UGC 6969 ) and possibly more. Detailed hydrogen line observations have been obtained from M109 and its satellites.
GRB 090423 is a gamma ray burst, which previously held the record for most distant object, and remains the most distant object with a spectroscopic redshift. The methods used to determine the distances to very distant cosmic objects are described in the " Cosmic distance ladder ".
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 ...
The most distant astronomical objects observable with telescopes date to this period; as of 2016, the most remote galaxy observed is GN-z11, at a redshift of 11.09. The earliest "modern" Population I stars are formed in this period. Present time: 13.8 Ga 0 2.7 K
