The chances of finding life on Jupiter has increased significantly


Modeling conducted by experts from the jet propulsion Laboratory of NASA in Pasadena, showed that the under-ice ocean on Europe, Jupiter’s moon similar to the Earth’s oceans as in their chemical composition and what is happening in it.

According to scientists, this suggests that the chances of the origin of life in this great ocean, and may not require volcanic activity.

Most experts have long agreed that under the ice of Europe is a huge amount of salt water in liquid form, however, the question of whether in the water to the required components exist and be adhered to suitable conditions for generating and sustaining life, long a matter of controversy among different researchers.

To get closer to the answer to this question, scientists have created a model that allows you to predict what can be the content of water in oxygen and hydrogen, if volcanism on the planet occurs. These two elements, according to the researchers, are for the origin of life key, and the right balance allows the ocean to be not too acidic and not too alkaline for the growth of micro-organisms. As shown by the model, in earth’s oceans and in Europe, the ratio of hydrogen and oxygen may be about the same, 1 to 10, while on Jupiter it explains a few other processes.

Hydrogen, according to the researchers, is released as you break up the core of Europe due to its cooling, and gradually enters the water. Oxygen, by contrast, falls into the ocean with the ice surface, where its source are disintegrating under the influence of solar wind water molecules.

The scientists published their study in the journal Geophysical Research Letters.
