描述Leo Goldberg Kitt Peak National Observatory Tucson, Arizona 85726, U. S. A. Of all the reasons for exploring the Universe, none is more com- pelling than the possibility of discovering intelligent life elsewhere in the Universe. Still the quest for extraterrestrial life has been near the bottom of the astronomers‘ list of priorities, not because the number of extraterrestrial civilizations is conjectured to be van- ishingly small, but because our powers of detection were thought to be far too weak. About ten years ago, however, the growing reach of ra- dio telescopes on the ground and of optical and infrared telescopes in space persuaded a number of thoughtful astronomers that the time for a more serious search had arrived. Accordingly, a joint Soviet-American conference on the problems of Communication with Extraterrestrial In- telligence was convened at the Byurakan Astrophysical Observatory of the Armenian Academy of Sciences during September 5-11, 1971 and was soon followed by a number of other important meetings, notably a series of NASA-sponsored workshops in the USA held between January, 1975 and May, 1976. Since SETI is fundamentally an international undertaking and as- tro

Uncertainty in Estimates of the Number of Extraterrestrial Civilizations. It is further argued that it is advantageous to consider explicitly these underlying assumptions in order to compare the probable numbers of civilizations operating radio beacons, permitting radio leakage, dispatching probes for radio surveillance or dispatching vehicles for manned surveillance.

N is Neither Very Small nor Very Largeficient to support hundreds of millions of individuals for hundreds of years. The laws of physics, biology, and interstellar distances thus make interstellar colonization unreasonable, and moderate values of N continue to be most plausible.

A Bimodal Search Strategy for SETItraterrestrial origin will not be any easy matter. Whether N is large or small, we do not know where to point our antennas, on what frequency to listen, nor the type of signal to search for. To determine these, we must engage in an extensive and systematic search program.

Strategies for SETI Through Radio Waves an Introductioning visited. But a more skeptical faction, finding no solid evidence either for visitation or for astro-engineering on a Dyson scale, concludes that either we are being quarantined (the zoo hypothesis) or else intelligent life is a very rare phenomenon (we really . alone).
