Spacecraft Data Suggest Saturn Moon's Ocean May Harbor Hydrothermal Activity
Things to know:
• Cassini finds first evidence of active hot-water chemistry beyond planet Earth
• Findings in two separate papers support the notion
• The results have important implications for the habitability of icy worlds
NASA's Cassini spacecraft has provided scientists the first clear evidence that Saturn's moon Enceladus exhibits signs of present-day hydrothermal activity which may resemble that seen in the deep oceans on Earth. The implications of such activity on a world other than our planet open up unprecedented scientific possibilities.
"These findings add to the possibility that Enceladus, which contains a subsurface ocean and displays remarkable geologic activity, could contain environments suitable for living organisms," said John Grunsfeld, astronaut and associate administrator of NASA's Science Mission Directorate in Washington. "The locations in our solar system where extreme environments occur in which life might exist may bring us closer to answering the question: are we alone in the universe."
