Scientists said on Wednesday, October 1, 2025, that new organic molecules were found on Saturn’s moon Enceladus. The discovery came from NASA’s Cassini spacecraft, which passed close to the moon in 2008. Enceladus is a small moon, about 500 kilometers wide. It is famous for water plumes that rise from its south pole. These plumes come from an ocean under the ice, making the moon an important place in the search for life outside Earth. The study, published in Nature Astronomy, showed that the organic grains were younger than old grains seen in Saturn’s rings. Younger grains gave scientists a clearer sample to study. Experts said the chemicals increased the possibility of habitability, but no life has been found.The study showed that fresh ice grains hit Cassini’s dust analyzer at high speed, about 65,000 kilometers per hour. These grains contained known organics and new ones. The evidence suggested that the chemicals came from the underground ocean and may be linked to hot vents on the seafloor. On Earth, such vents support sea life. Scientists explained that a place can be habitable without having life. Future missions to Enceladus are being planned, while NASA will also send the Europa Clipper to explore Jupiter’s moon Europa in 2030.
