:List of the most distant astronomical objects

File:JADES-GS-z14-0.png has been determined to be at a redshift of 14.32, making it the current record-holder for the most distant known galaxy (May 2024). This corresponds to a time less than 300 million years after the big bang.| alt=An infrared image from NASA’s James Webb Space Telescope that was taken by the NIRCam for the JWST Advanced Deep Extragalactic Survey (JADES) program.]]

This article documents the most distant astronomical objects discovered and verified so far, and the time periods in which they were so classified.

For comparisons with the light travel distance of the astronomical objects listed below, the age of the universe since the Big Bang is currently estimated as 13.787±0.020 Gyr.

Distances to remote objects, other than those in nearby galaxies, are nearly always inferred by measuring the cosmological redshift of their light. By their nature, very distant objects tend to be very faint, and these distance determinations are difficult and subject to errors. An important distinction is whether the distance is determined via spectroscopy or using a photometric redshift technique. The former is generally both more precise and also more reliable, in the sense that photometric redshifts are more prone to being wrong due to confusion with lower redshift sources that may have unusual spectra. For that reason, a spectroscopic redshift is conventionally regarded as being necessary for an object's distance to be considered definitely known, whereas photometrically determined redshifts identify "candidate" very distant sources. Here, this distinction is indicated by a "p" subscript for photometric redshifts.

The proper distance provides a measurement of how far a galaxy is at a fixed moment in time. At the present time the proper distance equals the comoving distance since the cosmological scale factor has value one: $a(t_0) = 1$ . The proper distance represents the distance obtained as if one were able to freeze the flow of time (set $dt = 0$ in the FLRW metric) and walk all the way to a galaxy while using a meter stick.{{Cite book |last=Guidry |first=Mike |title=Modern general relativity: black holes, gravitational waves, and cosmology |date=2019 |publisher=Cambridge university press |isbn=978-1-107-19789-3 |location=Cambridge New York}} For practical reasons, the proper distance is calculated as the distance traveled by light (set $ds = 0$ in the FLRW metric) from the time of emission by a galaxy to the time an observer (on Earth) receives the light signal. It differs from the “light travel distance” since the proper distance takes into account the expansion of the universe, i.e. the space expands as the light travels through it, resulting in numerical values which locate the most distant galaxies beyond the Hubble sphere and therefore with recession velocities greater than the speed of light c.{{Cite journal |last1=Davis |first1=Tamara M. |last2=Lineweaver |first2=Charles H. |date=2004 |title=Expanding Confusion: Common Misconceptions of Cosmological Horizons and the Superluminal Expansion of the Universe |url=https://www.cambridge.org/core/product/identifier/S132335800000607X/type/journal_article |journal=Publications of the Astronomical Society of Australia |language=en |volume=21 |issue=1 |pages=97–109 |doi=10.1071/AS03040 |arxiv=astro-ph/0310808 |bibcode=2004PASA...21...97D |s2cid=13068122 |issn=1323-3580}}

Candidate most distant objects

Since the beginning of the James Webb Space Telescope's (JWST) science operations in June 2022, numerous distant galaxies far beyond what could be seen by the Hubble Space Telescope (z = 11) have been discovered thanks to the JWST's capability of seeing far into the infrared.{{cite journal|title=First Batch of z ≈ 11–20 Candidate Objects Revealed by the James Webb Space Telescope Early Release Observations on SMACS 0723-73|first=Haojing|last=Yan|display-authors=etal|journal=The Astrophysical Journal Letters|date=January 2023|volume=942|issue=L9|page=20|doi-access=free|doi=10.3847/2041-8213/aca80c|arxiv=2207.11558|bibcode=2023ApJ...942L...9Y}} Previously in 2012, there were about 50 possible objects z = 8 or farther, and another 100 candidates at z = 7, based on photometric redshift estimates released by the Hubble eXtreme Deep Field (XDF) project from observations made between mid-2002 and December 2012.{{cite web |url=http://www.firstgalaxies.org/the-latest-results |title=Our Latest Results |author1=Garth Illingworth |author2=Rychard Bouwens |author3=Pascal Oesch |author4=Ivo Labbe |author5=Dan Magee |website=FirstGalaxies |date=December 2012 |access-date=March 10, 2016}} Some objects included here have been observed spectroscopically, but had only one emission line tentatively detected, and are therefore still considered candidates by researchers.{{cite journal|title=A Comprehensive Study of Galaxies at z ~ 9–16 Found in the Early JWST Data: Ultraviolet Luminosity Functions and Cosmic Star Formation History at the Pre-reionization Epoch|first=Yuichi|last=Harikane|journal=The Astrophysical Journal Supplement Series |year=2023 |volume=265 |issue=1 |page=5 |display-authors=etal|arxiv=2208.01612|doi=10.3847/1538-4365/acaaa9 |bibcode=2023ApJS..265....5H |s2cid=251253150 |doi-access=free }}

Timeline of most distant astronomical object recordholders

Objects in this list were found to be the most distant object at the time of determination of their distance. This is frequently not the same as the date of their discovery.

Distances to astronomical objects may be determined through parallax measurements, use of standard references such as cepheid variables or Type Ia supernovas, or redshift measurement. Spectroscopic redshift measurement is preferred, while photometric redshift measurement is also used to identify candidate high redshift sources. The symbol z represents redshift.

| Uranus

| Planet of the Solar System

| 1781 − 1838

| 18 AU

| This was the last planet discovered before the first successful measurement of stellar parallax. It had been determined that the stars were much farther away than the planets.

style="background:#c0c0e0;"

| Saturn

| Planet of the Solar System

| 1619 − 1781

| 10 AU

| From Kepler's Third Law, it was finally determined that Saturn is indeed the outermost of the classical planets, and its distance derived. It had only previously been conjectured to be the outermost, due to it having the longest orbital period, and slowest orbital motion. It had been determined that the stars were much farther away than the planets.

| Mars

| Planet of the Solar System

| 1609 − 1619

| 2.6 AU when Mars is diametrically opposed to Earth

| Kepler correctly characterized Mars and Earth's orbits in the publication Astronomia nova. It had been conjectured that the fixed stars were much farther away than the planets.

| Sun

| Star

| 3rd century BC — 1609

| 380 Earth radii (very inaccurate, true=16000 Earth radii)

| Aristarchus of Samos made a measurement of the distance of the Sun from the Earth in relation to the distance of the Moon from the Earth. The distance to the Moon was described in Earth radii (20, also inaccurate). The diameter of the Earth had been calculated previously. At the time, it was assumed that some of the planets were further away, but their distances could not be measured. The order of the planets was conjecture until Kepler determined the distances from the Sun of the five known planets that were not Earth. It had been conjectured that the fixed stars were much farther away than the planets.

| Moon

| Moon of a planet

| 3rd century BC

| 20 Earth radii (very inaccurate, true=64 Earth radii)

| Aristarchus of Samos made a measurement of the distance between the Earth and the Moon. The diameter of the Earth had been calculated previously.

List of objects by year of discovery that turned out to be most distant

This list contains a list of most distant objects by year of discovery of the object, not the determination of its distance. Objects may have been discovered without distance determination, and were found subsequently to be the most distant known at that time. However, object must have been named or described. An object like OJ 287 is ignored even though it was detected as early as 1891 using photographic plates, but ignored until the advent of radiotelescopes.
