摘　　要：1608年望远镜问世,1609年伽利略率先用望远镜观测天体和天象,并很快做出一系列重要的发现,开创了天文观测和研究的新纪元。随着技术进步和认识上的提高,从1940年代起的几十年中,相继诞生并发展了射电天文学、红外天文学、紫外天文学、X射线天文学和γ射线天文学,从而实现了对天体辐射观测的全波段覆盖,诞生了多波段天文学,人类对宇宙和宇宙中各类天体、天象的物理本质的认知迈入了全新的阶段。After the telescope was invented in 1608, the astronomical telescope was firstly used to observe variable celestial objects by the Italian famous scientist, Galileo Galilei, in 1609, a number of important discoveries were made soon, and a new era for astronomical observations and studies ushered in. As technical developments and knowledge improvements, radio astronomy, infrared astronomy, ultraviolet astronomy, X-ray astronomy and γ-ray astronomy were developed one by one during some decades from 1940s, and astronomers can cover the whole wavebands of electromagnetic radiation emitted from celestial objects, which means that multiwavelength astronomy came into being, and step into a new phase to know better physical nature of the Universe and different kinds of celestial objects in it.
