Saturn’s icy moon Enceladus may make alien life easier to find than scientists thought

Saturn’s icy moon Enceladus may be doing something remarkably useful for scientists searching for extraterrestrial life. Its towering plumes could naturally sort and concentrate material from the hidden ocean below, making traces of biological material easier for future spacecraft to detect. A second experiment adds another reason for optimism. Researchers recreated important chemical conditions from Enceladus’s ocean and found that a methane-producing microorganism from Earth could continue...
