演講題目 | Searching for Other Earths and Life in the Universe |
摘要 | It was 400 years ago that Galileo gazed innocently toward the heavens with a telescope, displacing the Earth from its central pedastal. Since then, telescopes have placed our Solar System and our Milky Way Galaxy in their proper contexts within the universe. But profound questions remain about the commonality of other Earths and about life in the universe. Science fiction offers a model of our Milky Way Galaxy teeming with habitable planets populated by advanced civilizations that engage in interstellar travel and exploration. But in our real universe, Earth-like planets and alien life have proved elusive. Where are they? Habitable earths may be more precious than currently realized. This month, on March 6, NASA launched the Kepler telescope from the Kennedy Space Center, designed to carry out humanities' first search for Earth-like worlds around other stars. A wild race to discover habitable and inhabited worlds is about to begin. |
