Anthropomorphic and hyperencephalized, that is, humans, heads and scarce body. This is the typical image of aliens. Similar to us, however, because they have developed the technology of access to the Earth from deep space, necessarily more intelligent than us, and therefore with more outstanding features related to intelligence. Often, especially in the cinema, conquerors. In short, some "evolve".
Even when we have sent information about us in Pioneer and Voyager Wide Space, we have prepared messages aimed at living beings capable of understanding our minds. By chance, because we know no other mind than ours. However, astrobiologists consider the possibilities of extraterrestrial life to be like that of Earth, let alone the possible intelligent life. However, given the astronomical number of stars in the universe, they are convinced that life may have arisen elsewhere.
In fact, in a few years the number of exoplanets found has been dumped and the possibility of finding habitable planets outside the known solar system has been expanded. From the detection of exoplanets by indirect methods, direct detection has been passed and in them the technology of identification of biological markers is evolving. In fact, the current search engines of extraterrestrials seek atoms and molecules, mainly carbon and water, "because according to the chemistry we know, water and carbon are the most suitable components for the [generation of life]," says astrobiologist Carlos Briones, from the Center of Astrobiology of Madrid. With him and in science fiction Sergio L. In this issue we have approached the aliens with Palacios to learn how they have evolved from the green men to the unknown systems, human imagery and science.
