In this work we will present a bibliographical review and presentation of the historical of the French semiotics that allows to approach the scientific image. We will illustrate with a brief analysis of scientific images presented in two Star Wars franchise films: the first photograph of Star Wars Episode I: The Phantom Menace (1999) and the second of Star Wars Episode III: Revenge of the Sith (2005), both directed by George Lucas. To that end, we will use tools from the theoretical framework proposed by the Semioticists Jean-Francois Bordron (2009), Jacques Fontanille (2007) and Maria Giulia Dondero (2010a). We will try to analyze the visual universe of the Star Wars films, since the narratives occur in a fictitious galaxy and several sideways space travels are constantly presented, thus, we will approach the vulgarization to be made of certain scientific images for the target audience so that they can be understood.
