Europa’s Crust and Ocean: How Tides Create a Potentially Habitable Physical Settingllite might support life. Most recently, interpretation of images and other data obtained by the Voyager and Galileo spacecraft has indicated that indeed there is an ocean underlying the crust of ice at the surface, and has suggested that the ocean is linked to the surface through a variety of processes that may provide habitable niches.

Microbial Life in Terrestrial Permafrost: Methanogenesis and Nitrification in Gelisols as Potentialschemical and physical analyses give insights into early stages of life on Earth. The extreme conditions in terrestrial permafrost soils can help to understand the evolution of life on early Mars and help searching for possible niches of life on present Mars or in other extraterrestrial permafrost habitats [1, 2].
