In this research work we intend to make a contextual analysis of science in which the ways in which the question of extraterrestrial life is currently addressed and how it is intrinsically linked to the way in which they are represented are located in a general way. future possibilities, socially shared, of our own society in the imaginaries that surround this scientific field. It is developed from a methodology of participant ethnography with the astrobiology studies group of the planetarium of Medellin in order to capture in a close way how the subjects that participate in science training fields converge and do their different readings of the problems, the expected results and how this translates into future actions and future scenarios. It will be analyzed from the elaborations of the sociology of science how the different scientific formulations in this field, behave what is called socially constructed knowledge. Thus, three great social representations of the future were built: in the first place, an imaginary of humanity as a species called to explore and discover the solar system, which is related to the analogical reasoning that induces investigative possibilities of finding unicellular life or primal organisms that are specified in trans-scientific relationships. Second, a vision of intelligent life and technological civilizations that is broadly combined with transfigured representations of our society. And finally, a representation of space exploration as a scenario of tension between investigative and economic interest that threatens to take the socially produced ills to other places where humanity embarks on its journeys, and which is represented in the field called astrobioetica
