The possibility of intelligent life also existing on the planet Venus is not considered completely unreasonable by astronomers. The atmosphere of Venus apparently consists mostly of carbon dioxide with deep clouds of formaldehyde droplets, and there seems to be little or no water. Yet, scientists concede that living organisms might develop in chemical environments which are strange to us. Venus, however, has two handicaps. Her mass and gravity are nearly as large as the Earth (Mars is smaller) and her cloudy atmosphere would discourage astronomy, hence space travel. The last argument, I thought, did not have too much weight. We were planning to escape the earth’s gravity; Martians could do the same, with their planet. As for the cloudy atmosphere, they could have developed some system of radio or radar investigation of the universe. The Navy research units, I knew, were probing the far-off Crab nebula in the Milky Way with special radio devices. This same method, or something far superior, could have been developed on Venus, or other planets surrounded by constant clouds. After the discussion of solar-system planets, the Project “Saucer” report went on to other star systems: Outside the solar system other stars—22 in number—have satellite planets. Our sun has nine. One of these, the Earth, is ideal for existence of intelligent life. On two others there is a possibility of life. Therefore, astronomers believe reasonable the thesis that there could be at least one ideally habitable planet for each of the 22 other eligible stars. After publication of our findings in _True_, several astronomers said that many planets may be inhabited. One of these was Dr. Carl F. von Weizacker, noted University of Chicago physicist. On January 10, 1950, Dr. von Weizacker stated: “Billions upon billions of stars found in the heavens may each have their own planets revolving about them. It is possible that these planets would have plant and animal life on them similar to the earth’s.” After narrowing the eligible stars down to twenty-two the Project “Saucer” report goes on: The theory is also employed that man represents the average in advancement and development. Therefore, one-half the other habitable planets would be behind man in development, and the other half ahead. It is also assumed that any visiting race could be expected to be far in advance of man. Thus, the chance of space travelers existing at planets attached to neighboring stars is very much greater than the chance of space-traveling Martians. The one can be viewed as almost a certainty (if you accept the thesis that the number of inhabited planets is equal to those that are suitable for life and that intelligent life is not peculiar to the Earth) .”
