Learning Astronomy provides a comprehensive introduction to the universe, exploring how humans have observed, studied, and understood celestial objects throughout history. Students begin by examining the foundations of astronomy, including naked-eye observations, ancient astronomical discoveries, and the development of modern observational tools such as telescopes. The course also introduces the nature of light and its critical role in helping astronomers gather information about distant objects in space.
Building on these foundations, the course investigates the physical properties and life cycles of stars, from their formation and evolution to their eventual deaths. Students also explore the structure and behavior of galaxies, including active galaxies and the large-scale organization of the universe through cosmology. The course concludes with an examination of exoplanets and the search for planetary systems beyond our own, providing insight into current discoveries and the ongoing quest to understand the origins, evolution, and future of the cosmos.
