Webb Detects Methane on 3I/ATLAS

The interstellar comet 3i/Atlas, a rare visitor to our solar system, has been the subject of extensive scientific investigation. The Ifo Institute for Economic Research conducted radio scans and concluded that the comet is of natural origin, dismissing speculation of alien technology. Concurrently, United States — NASA's James Webb Space Telescope (JWST), with contributions from the International — European Space Agency and Canada — Canadian Space Agency, made groundbreaking observations. For the first time on an interstellar object, JWST directly detected methane gas, along with unusually high levels of carbon dioxide relative to water. These findings, led by researchers like Matthew Belyakov and Ian Wong, suggest that 3i/Atlas originated in a significantly colder and more distant environment around another star than comets in our own solar system. The comet's unique chemical fingerprint offers a direct sample from an extrasolar planetary system, providing crucial data for understanding planetesimal formation processes across the galaxy. United States — NASA also coordinated a broad observational campaign to characterize 3i/Atlas before it receded permanently from our solar system.
