我国在贵州建造了全球最大直径的射电望远镜,该望远镜拥有500m宽的口径,被称为“中国天眼”.天文学家认为,望远镜有助于观察外星是否存在生命,并帮助解开宇宙起源之谜.为什么能够利用望远镜观察到遥远的天体?为什么又能够利用显微镜观察到微小的细胞?通过本节的学习,你将对它们的原理有所了解.
My country has built the world’s largest diameter radio telescope in Guizhou with a 500-meter wide aperture called “China’s Eye.” Astronomers believe the telescope helps to see if extraterrestrial life exists and helps unlock the universe Why you can use telescopes to observe distant celestial bodies? Why microscopic observation of tiny cells? Throughout this section you will learn about their principles.
