1996年的头条科学新闻可以总结成几个字:火星生命。 不过,这种说法未免片面。 当去年夏天美国国家航空航天局的科学家宣称他们找到了火星上存在过生命的证据时,去年最热门的科学话题又增添了一个新的插曲,这一重大突破性意义非凡,它改变了人们对于外星生命的看法。 1995年,就有许多研究成果使科学家几乎相信:生命的起源并不是只会发生在地球上的、偶然的奇异事件,而是宇宙中普遍存在的自然规律。 美国康奈尔大学的天文学家史蒂芬·斯奎尔说:“这一发现意义深远,正如当年哥白尼和达尔文划时 The headlines of 1996 science news can be summed up in a few words: Mars life. However, this statement is unilateral. When NASA scientists announced last summer that they had found evidence of a life on Mars, a new episode added to the hottest science topic of last year, a major breakthrough that has changed the way people think about Alien life’s view. In 1995, there were many research results that made scientists almost believe that the origin of life is not only an accidental bizarre event that takes place on earth but a universal law prevailing in the universe. Steven Squier, an astronomer at Cornell University in the United States, said: "This discovery is far-reaching. Just as Copernicus and Darwin had time-scratched
