The United Nations briefly considered the issue of extra-terrestrial intelligence at the 32nd session of the General Assembly in 1977. As a result, the Office of Outer Space Affairs was tasked to prepare a document on issues related to 'messages to extra-terrestrial civilizations', but this area has not been followed through in more recent times. This discussion paper describes the United Nations' activities in the field of near-Earth objects in some detail, and suggests that this might be used as a model of how Member States could proceed with dealing with this issue in case the existence of extra-terrestrial life/intelligence is established.
