JADES-GS-z14-0 explained

Constellation Name:Fornax
JADES-GS-z14-0
Epoch:J2000
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 furthest 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, placing the galaxy's formation at an estimated 290 million years after the Big Bang.[4] Its age, size, and luminosity added to a growing body of evidence that current theories of early star and galaxy formation are incomplete.

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.[6]

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 of 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.
