Researchers at the SETI Institute propose searching lunar soil for microscopic engineered particles as evidence of extraterrestrial technology, arguing the Moon's stable surface has accumulated interstellar material over billions of years. The study establishes a testable framework using advanced microscopy and AI to examine lunar regolith, potentially constraining the prevalence of technological civilizations in the Milky Way without claiming any technosignatures have been discovered.
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.
Pioneer Labs announced sPL.001, an engineered bacterium designed to grow using Martian soil nutrients without Earth supplements, marking a key step toward terraforming Mars. The microbe can produce bioplastics for construction in a heated bioreactor, enabling a Martian city to be built from a single rocket landing while posing no threat to potential existing Martian life.
