Could tiny salt crystals on Saturn’s moon Enceladus preserve clues to extraterrestrial life? Laboratory experiments show that natron crystals can trap microscopic water droplets as they freeze, potentially preserving chemical traces from the moon’s hidden ocean.

Although these deposits remain unconfirmed on Enceladus, future space missions could search for them near its south polar vents, offering a new way to investigate the possibility of life beyond Earth.
