Course Description

In Astronomy 20 we will take a journey through the universe to explore everything from the potential for extraterrestrial life to the evolution of stars and galaxies. This course explores deep questions about the universe from a scientific perspective such as, "What is the origin of life?", "How do stars form and die?", and "What is the fate of the universe?"
