Microbes From Ambient-pressure Analogues Offer Insights Into Possible Life In Europa’s High-pressure Subsurface Ocean

by Keith Cowing

Under its thick ice layer, Europa contains a shielded liquid water ocean where habitable conditions may exist. To effectively assess the habitability of this environment and the implications on putative […]
