JADES-GS-z14-0 is a high-redshift Lyman-Break galaxy in the constellation Fornax that was discovered in 2024 using NIRcam as part of the JWST Advanced Deep Extragalactic Survey (JADES) program.[1][2] It has a redshift of 14.32, making it the most distant galaxy and astronomical object ever discovered.
Discovery
[edit]JADES-GS-z14-0 was observed using the James Webb Space Telescope"s Near-Infrared Spectrograph (NIRSpec) in 2024,[3] and it measured a redshift of 14.32,[4] placing the galaxy"s formation at an estimated 290 million years after the Big Bang.[5] Its age, size, and luminosity added to a growing body of evidence that current theories of early star and galaxy formation are incomplete.[6]
Characteristics
[edit]JADES-GS-z14-0 is 1600 light years wide and very luminous.[6] Spectroscopic analysis revealed the presence of strong ionized gas emissions, including hydrogen and oxygen.[4]
Further observations
[edit]The initial identification of JADES-GS-z14-0 came from imaging data obtained with JWST’s Near-Infrared Camera (NIRCam). The high-redshift hypothesis was confirmed through multiple spectroscopic observations with NIRSpec. Additionally, observations using JWST"s Mid-Infrared Instrument (MIRI) detected the galaxy at longer wavelengths, which support the extreme distance at which JADES-GS-z14-0 is located.[4]
