来自北京玉泉小学三(4)班的李卓航同学问:欧阳爷爷,听说科学家已经发现火星上有液态水,我很好奇,火星上到底有没有生命?或者说火星上是否曾经出现过生命?欧阳自远院士的回答:李卓航同学,你好!首先,我想告诉你,火星环境太恶劣了,大气压只有地球的1%,气体主要是二氧化碳,即使有水,也是有毒的盐水,和地球上的水并不一样。因此,火星上现在没有生命活动,至少目前没有找到火星上有生命存在的证据。
Li Zhuohang, a student from Beijing Yuquan Primary School Class III (4), asked: Ouyang Grandpa, I heard that scientists have found that there is liquid water on Mars. I am curious about whether there is life on Mars or whether there has ever been life on Mars. Answer from Liyuan Academy: Li Zhuohang Classmate, Hello! First of all, I want to tell you that the environment in Mars is so bad that the atmospheric pressure is only 1% of the earth’s atmosphere, the gas is mainly carbon dioxide, and even the water is poisonous salt water, The water is not the same As a result, there is no life activity on Mars, at least for now, no proof of the existence of life on Mars has been found.
