ESA's Trace Gas Orbiter captured the closest view yet of comet 3I/ATLAS, revealing a fast-moving, fuzzy object. JWST data indicates an unusually CO₂-rich coma, while polarimetric observations show unprecedented light polarization. Precovery data suggests possible early activity. While orbital parameters are known and pose no Earth threat, a "bright streak" image from the Perseverance rover is not definitively confirmed as the comet, with some scientists suggesting it's an artifact. Details like size remain debated, and any claims of alien probes are unsubstantiated.
