NASA's Webb detects methane and strange chemistry on interstellar comet 3I/ATLAS
NASA's James Webb Space Telescope has uncovered unusual chemistry in interstellar comet 3I/ATLAS, including the first direct detection of methane on a visitor from another star system. The comet also contains exceptionally high levels of carbon dioxide, making it unlike most comets born in our solar system. Scientists believe the methane was hidden beneath the surface and only emerged after solar heating reached deeper icy layers.
The interstellar comet 3I/ATLAS, which passed through the Solar System in 2020, has been studied by scientists who seek to understand its origin and composition. Recently, a team of researchers published new discoveries...
The Atacama Large Millimeter/submillimeter Array in Chile detected unprecedented concentrations of methanol inside interstellar comet 3I/ATLAS during late 2025 observations released along the National Radio Astronomy Observatory. These recorded chemical volumes exceeded the alcohol levels cataloged in almost every comparable icy body native to the Solar System. ☆Observing 3I/ATLAS is like collecting a fingerprint from [...]
This Rare Interstellar Visitor Originated From An Exotic Alien System
Astronomers studying the 3I/ATLAS comet have uncovered clues suggesting the interstellar visitor originated in a deep-freeze environment far older than our solar system. When 3I/ATLAS zipped through the inner solar system, it became only the third confirmed interstellar object ever recorded, joining the enigmatic 1I/ʻOumuamua and 2I/Borisov.
