NASA's James Webb Space Telescope has detected methane on interstellar comet 3I/ATLAS, marking the first observation of this gas on an object from beyond our solar system. This discovery provides insights into the comet's formation in a different star system, revealing unusual chemical compositions compared to solar system comets.
- 013I/ATLAS is only the third confirmed interstellar object detected in our solar neighborhood.
- 02Methane was detected after the comet passed near the Sun, suggesting it was trapped beneath the surface for millions of years.
- 03The amount of methane relative to water was significantly higher than typically observed in solar system comets.
- 04The comet also released more carbon dioxide compared to water than is usually seen in comets from our solar system.
- 05Observations were made using the Mid-Infrared Instrument (MIRI) of the James Webb Space Telescope.

NASA's James Webb Space Telescope has made a groundbreaking discovery by detecting methane on interstellar comet 3I/ATLAS, the first direct observation of this gas on an object from beyond our solar system. This comet, which originated outside our solar system, is only the third confirmed interstellar object observed in our cosmic vicinity. The detection occurred during two observation sessions in December, where scientists noted that methane was released after the comet had passed near the Sun, likely due to solar heating that caused the gas to escape from beneath the comet's icy surface. Remarkably, the methane levels relative to water were much higher than those found in typical solar system comets. Additionally, the comet emitted significantly more carbon dioxide compared to water, indicating it formed in a distinctly different environment than those around the Sun. The findings, published in The Astrophysical Journal Letters, provide valuable insights into the composition and behavior of materials from other star systems.
