In one of his papers, he made the observation that it was possible that a growing technological society would increasingly surround its native star so as to maximise the capture of available energy. The end point of this process would be the complete enclosure of the star; all wavelength from visible light downwards being intercepted and waste heat beiong radiated outwards as infrared radiation. Therefore, one method of searching for extraterrestrial civilisations would be to look for suspiciously large objects radiating in the infrared. Dyson actually conceived of such a structure as being a cloud of asteroid-sized habitats, though science fiction writers
have prefererred a solid structure: either way, such an artifact is often referred to as a Dyson sphere
