NASA to search for alien life on Jupiter's icy moon with mission 'Europa Clipper'

The search of Extra-terrestrial life is on top amongst scientists. The space is so deep that it gives us hope that there is life beyond Earth, but simultaneously it confuses the researchers that alien life existence is a myth. In the latest research, scientists at Brown University in the US have discovered the sign of tectonic plates driving against one another; this process is known as subduction, creating the power needed for life.

Mr Brandon Johnson, an assistant educator in the Department of Earth, Environmental and Planetary Sciences at Brown University stated that if certainly, there is life in that ocean, subduction allows a way to provide the nutrients it will need. The nutrients involve oxidants, electron-stripping substances that are common on Europa’s surface and that can help produce an energy source for life.

On Earth, subduction process is driven primarily by temperature differences between relatively cold, dense, rocky plates and the super hot surrounding mantle. This moon’s icy exterior means that heat cannot be the driving force, but the scientists insist that it doesn’t mean subduction cannot occur. According to Mr Johnson’s team computer models propose that Europa’s ice plates can surely dive if they are alkaline than their surroundings.

 

He continued that adding salt to an ice slab would be like adding little weights to it because salt is denser than ice. So, rather than temperature, we show that variations in the salt content of the ice could allow subduction to occur on Europa. It is interesting to think that we might have plate tectonics somewhere other than Earth. Considering from the standpoint of relative planetology, if we can now investigate plate tectonics in this very different place, it might be capable of helping us understand how plate tectonics got ignited on the Earth.

The report comes as scientists working at NASA’s Goddard Space Flight Center in Maryland may have discovered compelling evidence Pluto could carry life. Now new research proposes that different planets such as Pluto and others such as Eris could have watery shores sloshing underneath their frosty exterior.

The Lead author Prabal Saxena, of NASA’s Goddard Space Flight Center in Greenbelt, Maryland, told that these objects require being admitted as potential repositories of water and life. If our research is correct, we now may have more houses in our solar system that possess some of the important elements of alien life.
