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.

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] Spectroscopic analysis revealed the presence of strong ionized gas emissions, including hydrogen and oxygen.

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.
