1、新概念英语第二册-Lesson61课课件是以天文学家是以天文学家哈勃哈勃为名，在轨道上环绕著地球的为名，在轨道上环绕著地球的望远镜望远镜。他的位置在地球的。他的位置在地球的大气层大气层之上，因此获之上，因此获得了地基望远镜所没有的好处得了地基望远镜所没有的好处影像不会受到影像不会受到大气湍流大气湍流的扰动，还能观测会被臭氧层吸收的紫的扰动，还能观测会被臭氧层吸收的紫外线。于外线。于19901990年发射之后，已经成为天文史上最年发射之后，已经成为天文史上最重要的仪器。他已经填补了地面观测的缺口，帮重要的仪器。他已经填补了地面观测的缺口，帮助天文学家解决了许多根本上的问题，对天文物助天文学家解决
2、了许多根本上的问题，对天文物理有更多的认识。理有更多的认识。从他于从他于19461946年的原始构想开始，直到发射为止，年的原始构想开始，直到发射为止，建造太空望远镜的计划不断的被延迟和受到预算建造太空望远镜的计划不断的被延迟和受到预算问题的困扰。在他发射之后，立即发现主镜有球问题的困扰。在他发射之后，立即发现主镜有球面像差，严重的降低了望远镜的观测能力。幸好面像差，严重的降低了望远镜的观测能力。幸好在在19931993年的维修任务之后，望远镜恢复了计划中年的维修任务之后，望远镜恢复了计划中的品质，并且成为天文学研究和推展公共关系最的品质，并且成为天文学研究和推展公共关系最重要的工具。重要的工
