Enceladus and Europa
Astronomy, exobiology & SETI
The icy moons Enceladus (Saturn) and Europa (Jupiter) hide oceans of liquid water beneath their crust. Enceladus’s geysers, detected by Cassini in 2005, eject organic material; the Europa Clipper probe, launched in October 2024, is to study Europa’s habitability from 2030.
