Detection of organic compounds in freshly ejected ice grains from Enceladus’s ocean – publication
1 oktober 2025
Scientists revisiting data from Cassini—which ended its mission in 2017—have spied even more tantalizing ingredients in the plumes: suites of complex organic molecules which, on Earth, are involved in the chemistry associated with even bigger molecules considered essential for biology.
Published in the article ‘Detection of organic compounds in freshly ejected ice grains from Enceladus’s ocean‘, the discovery bolsters the case for follow-up missions to search for signs of life within Saturn’s enigmatic, ocean-bearing moon. For nearly two decades Enceladus, a 500-kilometer-wide moon of Saturn, has been a top target in the hunt for extraterrestrial life. In 2005, shortly after arriving in orbit around the ringed planet, the joint NASA–European Space Agency (ESA) Cassini mission found clinching evidence that Enceladus harbored a liquid-water ocean beneath its bright-white icy crust—plumes of seawater spraying up from the moon’s south pole. Astrobiologists have become ever more enthralled by Enceladus ever since, as further studies of the ice grains in the plumes have revealed multiple molecular building blocks of life blasting out from the hidden ocean.
