An eye into space
本文作者： 21ST
DO you want to see aliens (外星人)? The world’s biggest telescope (望远镜) may help you. Scientists will build it in Chile (智利). It is as big as half of a soccer field. This telescope is 10 times clearer than other telescopes. It helps scientists learn more about space. People may use it before 2020. 21ST |  |
