Saturn’s ocean moon Enceladus is able to support life − my research team is working out how to detect extraterrestrial cells there
Saturn’s moon Enceladus has geysers shooting tiny grains of ice into space. These grains could hold traces of life − but researchers need the right tools to tell.
Enceladus, only 313 miles (504 kilometers) in diameter, harbors a liquid water ocean beneath its icy crust that spans the entire moon. These measurements helped us predict what dust analyzer instruments on a spacecraft should find if they encountered a bacterial cell contained in an ice grain. In addition to their small size, these cells like cold environments, and they need only a few nutrients to survive and grow, similar to how life adapted to the conditions in Enceladus’ ocean would probably be.
