The total water storage is more than the five oceans of the earth! If it is all thawed, it can be filled with a third of the moon
Editor’s note:NASA scientists discovered the salt-covered ocean on Europa, which exists in the ocean Can support all the ingredients of life! This is an amazing discovery, which means that there is probably a microorganism on Europa. On Europa, the total storage volume of the ocean under ice is more than that of the five oceans of the earth. If all the frozen ocean surface is thawed, it can be filled with one-third of the moon.

Jupiter’s moon Europa has discovered a sea covered by salty ice, recently, NASA scientists pointed out that all the ingredients that can support life have been found in the Europa Ocean. This environment is very beneficial to the life we know. Europa’s Europa ocean reaches a depth of hundreds of kilometers. If the total water volume is calculated, there is not much water on Earth. If Europa’s ice layer is completely melted, it can be filled with a third of the moon. .

NASA discovered the moon The second global ocean is located below the ice layer and is formed by the decomposition of hydrous minerals. The energy required for the decomposition comes from the tidal force of Jupiter. The ice inside Melt melted while squeezing Europa, but the surface temperature was too low to form an ocean on Europa’s surface. The ocean depth of Europa is about 10 kilometers or more. If you want to drill the ice, it will take years to use nuclear power equipment, so exploring the ocean of Europa is not easy. But scientists discovered a trick. In 2016, the Hubble telescope found a clue that there were multiple cracks on Europa’s surface. Water vapor was ejected from the cracks, which proved that the ocean and the ejected water vapor belong to the same substance, which means We only need to investigate the spray of Europa’s cracks to find out whether there are microorganisms in the ocean.
The research team also found that the ocean on Europa can be formed by”metamorphism”, and the composition of the rock may change. These”waters” are locked in the rock formations, and the tidal motion caused by Jupiter’s gravity causes the minerals to decompose and release trapped water. At the same time, radioactive materials will also release a certain amount of energy to promote the melting of Europa’s ice. At a certain depth, the ocean on Europa is a liquid environment that can achieve global distribution. The ocean on Europa may be rich in chlorides, moderately acidic, and contain a high concentration of carbon dioxide. Its composition becomes more like the ocean on earth. The life forms we know are survivable in Europa’s ocean.

NASA The Europa Clippers mission has been formulated, and it is planned to launch into orbit in the next few years, go to Jupiter, and analyze the jet material in orbit. If we can find microorganisms, it can definitely indicate that there is life in Europa’s ocean. In case no microorganisms are found in the jet, Europa’s investigation may be postponed. At least we theoretically found that Europa’s oceans are livable and have all the ingredients that can support life. Europa is also a tide locked satellite, just like the moon, with only one side facing Jupiter. Europa’s revolution period is 3.6 days, and it always faces Jupiter on the same side. Europa’s interior may be similar to the earth, all in a rocky environment with an iron core and mantle structure. Unlike Earth, Europa’s ocean is deep enough to cover the entire surface, which means that if Europa is completely thawed, there is no continent at all. Jupiter’s strong tidal force is one of the favorable conditions for Europa to hide life. One.
