深邃的夜空中,繁星点点。那里是浩瀚无垠的宇宙。你知道吗,那里的温度大约是-270℃。也就是说,宇宙空间处于一个极低温的状态。而我们人类及各种动植物则是由于大气层的保护,才得以在地球上生存。地球上最冷的地方在南极,那里测得的最低气温为-88.3℃。在月球的阴面,温度是–160℃。近半个世纪以来,人类一直在寻找地球之外的生命迹象,其中一个十分重要的判断依据就是温度是否适合生物体生存。
Deep in the night sky, starry. There is a vast universe. Did you know that the temperature there is about -270°C? In other words, the space is at a very low temperature. And we humans and all kinds of animals and plants are able to survive on Earth because of the protection of the atmosphere. The coldest place on Earth is in Antarctica, where the lowest temperature measured is -88.3°C. In the dark side of the moon, the temperature is –160°C. For nearly half a century, human beings have been looking for signs of life outside the Earth. One of the most important criteria for judgment is whether the temperature is suitable for the survival of living organisms.
