Geysers are exhausted from the ocean, and if there is life in the ocean, geysers can throw away their samples or, at least, the biodegradable products of metabolic reactions [19659002] Unfortunately, the surface of Europe is not a place of life. The energetic particles brought by the magnetic field of Jupiter should quickly destroy the complex compounds. However, to detect these traces, it is not necessary to drill down to the ocean – a new study presents calculations showing that only a few centimeters of ice are enough to preserve the molecules.
The study produced a three-dimensional model of the European magnetosphere and Jupiter. in different parts of Europe. The radiation close to the equator is relatively intense and the biobadays – especially the amino acids badyzed – are destroyed at a depth of 10 to 20 cm. Meanwhile, closer to the polar beam, the radiation shrinks and the traces of polarization must remain within one centimeter.
These calculations will help plan a NASA mission, Europa Clipper, which should fly over Europe and explore its different surfaces. Knowledge of the likely survival of biodegradation will allow us to select the right orbit to collect as much useful data as possible about the characteristics of the European ocean, even if there is no life .
The results of the study are published in Nature Astronomy
