Student Learning Outcomes

  • Understand the position of the Earth in the universe at large and the arrangement and scale of matter the universe.
  • Understand the life story of the stars and be able to explain how that life story relates to their own lives.

Description

Non-technical introduction to astronomy, with emphasis on stars, galaxies, and the origin and evolution of the universe. Topics covered include the nature of light, atoms, and telescopes; the birth, evolution, and death of stars (including an introduction to black holes); the Milky Way Galaxy and its development over time; normal galaxies, active galaxies, and cannibal galaxies; and the Big Bang model (of the origin and ultimate fate of the cosmos). No background in science or math is assumed.

Course Objectives

The student will be able to:
A. demonstrate an understanding of the scientific method and how it applies to astronomy;
B. describe the evolution of stars from birth to death and discuss how this evolution relates to their own lives on the Earth;
C. demonstrate a conceptual understanding of the scales of time and distance in the cosmos and what scientific evidence we have for these scales;
D. explain our modern understanding of the large scale structure and evolution of the universe of galaxies (including the expansion of the universe), and what the observational evidence is that underlies them;
E. understand the role of different types of telescopes and detectors in making astronomical observations;
F. describe the challenges women and people of color in astronomy have faced in the past, and describe how the situation is changing.
