Today’s scientific imaging technologies are able to detect and image emissions and radiations from a much wider range of the electromagnetic spectrum than ever before. Such phenomena lie beyond the horizons of ordinary human perceptibility. I examine here the implications of such translation mediations for the production of scientific knowledge and show how human embodiment is implicit for all perceptual observational possibilities. The framework is that of a postphenomenology which is able to relate these new phenomena to human embodiment.
