Astrobiology and the Search for Extraterrestrial Life Course Syllabus
Full curriculum breakdown — modules, lessons, estimated time, and outcomes.
Overview: This course offers a comprehensive introduction to astrobiology, exploring the origins of life, the potential for life beyond Earth, and the methods used to search for extraterrestrial life. Structured into six modules, the course balances theoretical concepts with practical applications. With approximately 11 hours per module, learners can expect to invest around 66 hours total to complete all content, including lectures, readings, and the final project. The course is designed for beginners but provides a solid foundation for further study or professional development in astrobiology and related fields.
