Type Lyman-break galaxy

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

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] Its age, size, and luminosity added to a growing body of evidence that current theories of early star and galaxy formation are incomplete. [5]

Characteristics

JADES-GS-z14-0 is 1600 light years wide and very luminous. [5] Spectroscopic analysis revealed the presence of strong ionized gas emissions, including hydrogen and oxygen. [4]

Further observations

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]
