Searching for life in alien oceans may be more difficult than scientists previously thought, even when we can sample these extraterrestrial waters directly.

Scientists studying Saturn's icy moon, Enceladus, have discovered that its ocean forms layers that slow the upward movement of life’s chemical signatures. If microbial life exists in Enceladus’ deep sea,

Asteroid Bennu’s dust reveals amino acid precursors and ancient water traces, fueling hopes that Saturn’s moon Enceladus and other icy worlds might harbor life.

A new study on Enceladus, a moon of Saturn, reveals that the physics of its ocean might prevent evidence of deep-sea life from reaching the surface. Enceladus’s ocean forms layers that significantly slow material movement from the ocean floor to the surface,

When searching for alien life, it’s not unusual to use Earth as a test bed for theories and even practice runs. Perhaps one of the most tantalising places in the Solar System to look for life is Saturn’s moon Enceladus.
