Astronomers have discovered the oldest known ‘dead’ galaxy, JADES-GS-z7-01-QU, which stopped forming stars more than 13 billion years ago. This discovery challenges current models of the early universe as the galaxy’s sudden halt in star formation is puzzling given the abundance of dust and gas at that time. Data from the JWST Advanced Deep Survey (JADES) suggests that the galaxy had a quick burst of star formation before abruptly stopping. JADES-GS-z7-01-QU is the oldest recorded dormant galaxy, and its smaller size was made detectable by the improved sensitivity of the JWST. The observations provide the deepest views into the distant universe made by JWST. Astronomers plan to find more old galaxies to better understand galactic evolution in the early universe and refine models of that time period.

Factuality Level: 8
Factuality Justification: The article provides information about the discovery of the oldest known ‘dead’ galaxy and the challenges it poses to current models of the early universe. It includes quotes from astronomers involved in the study and explains the significance of the findings. The article does not contain irrelevant information, misleading details, sensationalism, redundancy, or opinion masquerading as fact. It presents the information in a clear and factual manner without bias or invalid arguments.
Noise Level: 3
Noise Justification: The article provides detailed information about the discovery of the oldest ‘dead’ galaxy and its implications on current models of the early universe. It includes quotes from astronomers involved in the study and explains the significance of the findings. The article stays on topic and supports its claims with data from the JWST Advanced Deep Survey. However, it includes some slightly repetitive information and could benefit from more critical analysis of the implications of the discovery.
