Researchers found that Earth microbes from deep-sea hydrothermal vents can survive simulated conditions of the ocean beneath Saturn's moon Enceladus, suggesting the distant world may be habitable. The microbes, which convert hydrogen and carbon dioxide into methane, survived in a laboratory-recreated brine mimicking Enceladus's alkaline ocean environment, adding to evidence that life could potentially exist there.
New research shows that Enceladus's icy plumes slowly freeze and separate ocean components into concentrated particles, making it easier to analyze the moon's hidden ocean for signs of life. Studies by Professor Postberg's team at Freie Universität Berlin reveal that microorganisms could better tolerate Enceladus's ocean conditions than previously thought, increasing the likelihood of discovering extraterrestrial life.
Planetary scientists from Freie Universität Berlin published studies in Science Advances revealing that Saturn's moon Enceladus may be more habitable than previously thought. New evidence shows that ocean components separate during freezing in ice plumes, making them easier to analyze, and certain microorganisms could tolerate Enceladus's ocean conditions better than assumed.
