Hitekno.com – One of the moons orbiting around the planet Jupiter turns out to have potential that can accommodate life. That assumption came after scientists discovered signs of salty sea on one of the moons orbiting Jupiter, Europe.


As is well known, there are 79 moons orbiting Jupiter.


Four of the most brilliant and famous are Io, Europa, Ganymede and Callisto.


Previous research has found that under the frozen surface of Europe there was a potential liquid ocean that could accommodate life.


The researchers did not find strong evidence to support this assumption.


But now, a study has been published in the journal Advanced Science strengthen the evidence above.

Researchers at Caltech and NASA Jet Propulsion Laboratory revealed a yellow feature on the surface of the Moon of Europe.


This indicates that there is a lot of salt as the salt that exists on planet Earth.


Researchers believe that salt comes from the salty sea below.


This makes it similar to the composition of the oceans on Earth.


"Magnesium sulfate only dissolves in the sea from rocks on the ocean floor, but sodium chloride can show the oceanic hydrothermal soil"said Samantha Trumbo, lead researcher at Caltech.

Hydrothermal activity leads to complex chemical and heat reactions, two important ingredients of life.


The salt found in Europe is yellow because of the irradiance of the fine atmosphere.


This causes it to have a different salt color on Earth (white).


Cited by IFLScience, the researchers tested sodium chloride in laboratories under conditions such as Europe.


The color produced by sodium chloride is almost the same as the yellow characteristic found by scientists in Europe.

Research on Europe that has signs of life does not end here, there will be a spacecraft that has a special mission there.


NASA will launch the Europa Clipper spacecraft in 2023 and ESA will also launch the Jupiter Icy Moons Explorer in 2022.


If the spacecraft can find evidence to strengthen the theory of the scientists above, the salty sea in Europe may have life that has been expected by humans.
