Observation
Source: JWST (James Webb Space Telescope) — JADES (JWST Advanced Deep Extragalactic Survey)
Object: JADES-GS-z14-0
Key observational facts:
- Redshift: z ≈ 14.32 (spectroscopically confirmed)
- Lookback time: ~290 million years after the Big Bang
- Cosmic age at observation: Universe was only ~2% of its current age
- Properties: High luminosity in both visible and infrared wavelengths; Significant stellar mass (~10⁸–10⁹ M☉); Detected oxygen abundance, indicating prior star formation and enrichment cycles; Extended structure suggesting organized morphology
