UFOs are a central and virulent topic of contemporary aesthetics: as objects mediated by the media, they are also touchstones for the mechanisms of mediated reality itself. This applies both to the possibility of conducting a discourse about UFOs at all, i.e. recording and documenting these ‘unknown flying objects’, and to the dissemination of narratives about UFOs in science fiction. Against this background, UFOs are understood as media-aesthetic objects that are used to negotiate what is ‘real’ and how the media contribute to the construction of reality.
