Jupiter's Moon Europa May Have a 'Dead' Ocean, Study Suggests
Europa, one of Jupiter's largest moons, has long been considered a prime candidate in the search for extraterrestrial life due to its massive subsurface ocean. However, a new study is tempering that optimism, suggesting the ocean may be chemically "dead" — lacking the key energy sources that life as we know it would need to survive.
The research examines the chemical processes that could occur in Europa's ocean and finds that the availability of oxidants and other reactive molecules may be far more limited than previously hoped. Without sufficient chemical energy gradients, even microbial life would struggle to gain a foothold. While the findings don't completely rule out the possibility of life on Europa, they suggest that conditions may be far less hospitable than scientists have long assumed, potentially reshaping priorities for future exploration missions.
