新华社电美国科罗拉多大学的研究人员近日称,在太阳系外寻找到外星人的可能性更大.科罗拉多大学生化学家诺曼·佩斯教授说:“现在科学家仍不能保证在火星的火山口或木星的卫星木卫二的冰层中寻找到初级生命.”他分析认为,如果考虑到生命存在所需要的基本条件,火星和木卫二存在生命的机会都非常小.而且除地球外,太阳系中任何一个星球存在生命的可能性都不大.但对于广袤的宇宙而言,可能会在某处存在适于生命生存的条件.佩斯说,地球和其他星球存在大量多样生命形式 Xinhua News Agency, a researcher at the University of Colorado, said recently that it is more likely to find extraterrestrials outside the solar system. Professor Norman Pace, a Colorado college chemist, said: "Now scientists can’t guarantee the crater of Mars or Jupiter. The moon’s moon Europa finds primary life in the ice.” He believes that if we take into account the basic conditions for the existence of life, Mars and Europa have very little chance of life, and in addition to Earth, the solar system The possibility of life on any planet is not great. But for the vast universe, there may be conditions for life to survive somewhere. Pace said that the Earth and other planets have a large variety of life forms
