Hidden Oceans on Europa and Enceladus: Tidal Heating and the Quest for Life
To the point
Astrobiologist Lewis Dartnell notes that life needs energy and organic chemistry, so the tidal-heated subsurface oceans of Europa and Enceladus are prime places to search for life, and upcoming missions such as ESA's JUICE and NASA's Europa Clipper will map their ice, plumes, and oceans to assess their habitability.
