“Sometimes I think the surest sign that intelligent life exists elsewhere in the universe is that none of it has tried to contact us.”, Bill Watterson, The Indispensable Calvin and Hobbes

Is Earth the only world that supports life? The scientific question of life on other worlds stretches back to the Renaissance, when Johannes Kepler, best known in astronomy for his trio of laws that define the paths of moons and planets, decided to unwind a little by writing a book called Somnium, in which he describes the inhabitants of the Moon, whose surface had just been revealed by Galileo. In spite of hopes, fears, and thousands of pages and dozens of reels of science fiction, Kepler’s dream has never been realized, although tantalizing hints have surfaced as the years have passed:

  • Organic compounds, such as methane, are in the atmospheres of the giant planets of the outer solar system and of one of Saturn’s moons, Titan. These compounds are also found in comets, meteorites, and nebulæ, the clouds of gas and dust out of which stars and planets are formed.
  • Simple forms of life can survive exposure to very harsh conditions. For instance, bacteria were found to have survived for two years on the Moon in parts of Surveyor III which were brought back to Earth by the crew of Apollo XII.
  • Liquid water may lie under the icy surfaces of another of Saturn’s moons, Enceladus, and three of Jupiter’s moons, Callisto, Europa, and Ganymede. There is abundant evidence that water once flowed freely on the surface of Mars, and some signs that Venus once had more water than its current oven-like temperature would allow today.
  • Planets orbit other stars in the Milky Way.
