The water in the ocean on Jupiters moon is the same as on Earth


Astronomers have found that the water under the ice of Europa spills out onto the surface

On the icy crust that covers the entire surface of Europa — Jupiter — discovered salt. These data were Mike Brown (Mike Brown) at the California Institute of Technology in Pasadena (California Institute of Technology in Pasadena) and Kevin Hand (Kevin Hand) of NASA (NASA's Jet Propulsion Laboratory, Pasadena), working with the powerful Keck II, mounted on Hawaii (Telescope Keck II on Mauna Kea, Hawaii) and spectrometer OSIRIS.

In European salts are magnesium sulfate, sodium chloride and potassium. But where on earth is it — salt — come from? From the salty ocean, which is located under the icy crust of Europa. Its water, according to scientists, occasionally spills out onto the surface through the holes and cracks in the ice like lava terrestrial volcanoes. Salt — settles. And it becomes "visible" for spectroscopy instruments, as it reflects light differently than ice.

Salt — direct evidence that the water spills out, and hence the fact that the ocean on Jupiter's moon really exist.

— Europa's ocean and its surface is actively exchanging chemicals — says Brown. — Similar processes can provide the necessary energy for the emergence of organic life forms.

The scientist also believes that the composition of the European ocean water close to the water of Earth's oceans.

Europe (aka Jupiter II) opened the Galileo Galilei in 1610. Europe with about our moon. It has a diameter slightly greater than 3 thousand kilometers.

Scientists believe that under the icy crust of Europa is the ocean depth is about 100-160 kilometers. It covers the entire surface of a moon of Jupiter. The thickness of the ice crust in some places up to several kilometers. It is covered by extended cracks.

Europa's ocean is one of the few places in our solar system where life may be some. Over the ocean with a thin atmosphere consisting of oxygen.
