📍 How it ended
Scientific studies and observations from agencies like NASA and Webb suggested the interstellar comet was likely older than the Solar System. Speculation regarding methane signatures and the possibility of organisms emerged alongside claims it might be the oldest object ever seen.
Recent analysis focused on the object's light curve and its location on a comet evolutionary diagram.

The brief
Data from NASA’s Webb telescope suggests that 3I/ATLAS is an ancient, cold object. Observations indicate the comet possesses a chemical composition distinct from any previously studied celestial body.
Coverage from NASA Science, Phys.org, ScienceAlert, CBS News, and Yahoo highlights the comet's potential status as the oldest object recorded in the Solar System. Reports note that radio scans have yielded no evidence of alien technology associated with the object.
Future updates will focus on additional analysis of the comet's chemistry. Coverage does not yet specify how the object's trajectory relates to its origins or the exact mechanisms behind its unique chemical signature.
