《地球概论》是面向高等师范院校地理科学专业的基础天文学核心课程，也是高校天文通识教育课程。该课程旨在从地球视角，系统介绍天文学的基本方法、基本理论及基础应用，明确地球的宇宙环境及其地理意义。课程内容包括三篇，共十章：          

        第一篇：天文学的基本方法，包括星空区划、天体跟踪、天文观测；

        第二篇：天文学的基础理论，包括恒星与星系、太阳与太阳系、月球与地月系、地球； 

        第三篇：天文学的基本应用，包括天象演化、观象授时、历法制定。 

    本课程以重庆市科普基地和虚拟天文台软件为线下线上的实验平台，理论与实践并重，强调现代天文学思想演进与中国传统天文学的贡献，配备中英文字幕，是一门面向应用的中国特色的国际化大众天文学课程。

What  will this course talk about?

    Our course systematically introduce the basic methods, theories,and applications of astronomy from the perspective of the earth in order to clarify the earth’s cosmic environment and its geographical significance. The course structure consists of three units and ten chapters:

• The first unit introduces the basic methods of astronomy, including starry sky division, celestial bodies tracking, and astronomical observation;

• The second unit introduces the basic theories of astronomy, including stars and galaxies, the sun and the solar system, the moon and the Earth-Moon system and the Earth;

• The third unit introduces the basic application of astronomy, including the evolution of celestial phenomena, timing and the calendaring by celestial phenomena.
