Some alien’s marks were found on the surface of one of Jupiter’s moons.
Europe is one of scientists best hopes to find extraterrestrial traces in our solar system. Even so, the roughness of its world might make everything impossible to be discovered.
Amino acids can be marks of life, they can remain for 10 million years. They cannot be hidden by the radiation, and they can be displayed on the planet surface, which means that the specialists do not have to dig way to deep to discover marks of extraterrestrials life. For the moment this action is impossible because NASA lack the power to dig that deep.
The Nasa scientist, Tom Nordheim, expert on the habitability of icy worlds like Europa, said that Nasa has to make sure that each visitor which goes on the moon, it will land in the correct place.
NASA will send 2 missions in 2022: the first one that will explore best regions to land in, and could be followed by a lander. The company predicted they will find alien life possibly in 20 years.
Europa is energized to see the researchers chasing for outsider life because it is thought to contain a colossal fluid sea underneath the cold covering that encompasses it. Underneath that covering could be conditioned to make the moon tenable, according to researchers.
There is hope of life on that surface. Hit by huge quantities of radiations, the thing that covers our solar system, but from which we are alive by our atmosphere. Because of this, specialists are scared that traces that will lead to aliens life could be destroyed.
A new finding, posted in Nature Astronomy, is that the radiation can not get so deep into the surface as it was expected.
