The role of water in cell biology has traditionally been viewed as a passive medium for biochemical reactions. However, recent studies have highlighted the active role of water in cellular processes, including microbial growth and survival. This new perspective on the role of water in cell biology could have significant implications for our understanding of habitability on Europa.
Water Plumes on Europa
One of the most intriguing findings in recent years is the discovery of water plumes on Europa. These plumes, which are believed to be eruptions of water vapor from the subsurface ocean of Europa, have sparked renewed interest in the potential for life on this icy moon of Jupiter. The presence of these plumes suggests that the subsurface ocean may be connected to the surface, potentially providing a pathway for the exchange of nutrients and energy between the ocean and the surface environment.
