The video discusses the potential for life on Saturn's moon Enceladus, based on data from the Cassini space probe. In 2005, Cassini detected geysers containing dihydrogen, water ice, and methane. Methane is typically produced by bacteria on Earth but can also result from geological processes. Researchers used mathematical models to assess the likelihood of non-biological methane production, suggesting a possibility of life. The study also explores geochemical processes that could produce methane without biological activity.
