Search for Artificial Stellar Sources of Infrared Radiation

Science. 1960 Jun 3;131(3414):1667-8. doi: 10.1126/science.131.3414.1667.


If extraterrestrial intelligent beings exist and have reached a high level of technical development, one by-product of their energy metabolism is likely to be the large-scale conversion of starlight into far-infrared radiation. It is proposed that a search for sources of infrared radiation should accompany the recently initiated search for interstellar radio communications.
