课程的主题包含了：行星、行星形成；恒星、太阳、正常的恒星、恒星形成；恒星演化、超新星、致密天体(白矮星、中子星及黑洞)、波霎、双X-射线源；星团、球状及疏散星团；星际介质、气体、尘埃、磁场、宇宙射线；距离阶梯；星系、正常及活跃星系、喷流；重力透镜；大尺度结构；牛顿宇宙学、宇宙的动力膨胀及温度发展历史；宇宙背景微波辐射；大霹雳核合成。这门课并不需要先有天文学的知识。
Introduction to Astronomy provides a quantitative introduction to physics of the solar system, stars, interstellar medium, the galaxy, and universe, as determined from a variety of astronomical observations and models.
Topics include: planets, planet formation; stars, the Sun, "normal" stars, star formation; stellar evolution, supernovae, compact objects (white dwarfs, neutron stars, and black holes), plusars, binary X-ray sources; star clusters, globular and open clusters; interstellar medium, gas, dust, magnetic fields, cosmic rays; distance ladder; galaxies, normal and active galaxies, jets; gravitational lensing; large scaling structure; Newtonian cosmology, dynamical expansion and thermal history of the Universe; cosmic microwave background radiation; big-bang nucleosynthesis. No prior knowledge of astronomy necessary.
