There is table salt on one of Jupiter's moons

Let's go back to an experiment conducted years ago to better understand this one. In 2015, JPL scientist Kevin Hand put sea salt samples in a laboratory in conditions similar to those in Europe and bombarded them with radiation. His sample of sodium chloride has changed color and has taken a tint like a yellowish area on the moon called Tara Regio. Since STIS has also identified a spectral signature for irradiated sodium chloride on Tara Regio scars, the results of the new study suggest that the region is truly abundant in sea salt.

Since Tara Regio or the chaotic terrain is younger than the rest of the moon's surface, scientists believe that salt comes from the interaction of the surface with the ocean below. It was previously believed that the oceans of the moon contained salts of magnesium sulphate, not sodium chloride. As Discover the magazine It is worth mentioning that if the hidden ocean of Europe actually contains table salt, it is also possible that it has hydrothermal vents similar to those of the Earth, which provide the chloride necessary for the formation of the compound. It remains to be seen if the Jovian moon is conducive to life – NASA is preparing to launch the Europa Clipper to study its livability.
