Icy Moon of Saturn may prove to be more interesting than previously thought

Enceladus is one of the most interesting moons of Saturn because of the presence of a global ocean beneath its icy surface. Analysis of the composition of subglacial fluids showed that the local ocean water is emitted through cracks and fissures of Enceladus, rich in organic matter so necessary for the education and maintenance of biological life. As the portal phys.org on the positive properties of the saturnine moon is not the end, giving astronomers more reason to believe that Enceladus may be more interesting than previously thought.

What is under the ice of Enceladus?

In the Solar system has a large number of icy objects that deserve attention of specialists. So, along with those already mentioned above Enceladus, the icy satellite of Jupiter Europe can be a real haven for extraterrestrial life; Callisto is considered by scientists as a potential site for human colonization, and Titan, another moon of Saturn — is famous for its dense atmosphere and characteristics, very reminiscent of earth. To study the properties of the most interesting moons of the Solar system experts from the southwest research Institute have developed a new geochemical model that is configured to detect carbon dioxide under the ice of the icy satellites.

Analysis of CO2 from Enceladus have shown that the oceanic satellite of Saturn can be controlled by the complex chemical reactions occurring on its seabed. A study of gas plume and frozen sea spray that is emitted through cracks in the icy surface of the satellite, allows to assume that the internal space of Enceladus is much more complicated than previously thought.

Dr. Christopher Glein, lead author of an article in Geophysical Research Letters, finds that analysis of the underwater plume is to estimate the concentration of dissolved CO2 in the ocean may be one of the most promising ways of learning not available devices depths. Analysis of mass spectrometric data from the spacecraft Cassini NASA shows that the CO2 abundance is best explained by the geochemical reactions between the rocky core of the moon and the liquid water from its subsurface ocean. Combining this information with previous discoveries of silica and molecular hydrogen indicates a more complex, diverse geochemical core.

The presence of dissolved carbon dioxide also indicates the presence of geothermal sources inside Enceladus. At the bottom of the World ocean hydrothermal sources emit are rich in energy, rich in minerals fluid that is allowed to flourish unique ecosystems. What if similar processes occur under the ice of Enceladus?
