During Cassini’s deepest dive through the Enceladus plume, SwRI scientists discovered hydrogen gas in the material erupting from the Saturnian moon. This discovery provides further evidence for hydrothermal activity (illustrated here) and heightens the possibility that the ocean of Enceladus could have conditions suitable for microbial life.
