ASTR 104 Elementary Astronomy

Students develop an overview of the field of astronomy focusing on the structure and evolution of astronomical systems ranging in size from planets through galaxies. Students learn to use a variety of diagrams (e.g. HR diagram, Earth-Moon-Sun diagrams, stellar spectra) and algebraic calculations (e.g. Newton’s laws, Kepler’s laws, luminosities) to solve problems. Prominent topics include seasons, Moon phases, formation and structure of our Solar System, types and life cycles of stars, and galactic dynamics. This is a lecture/discussion course designed for non-science majors. For Elementary Astronomy Laboratory, see ASTR 114.

Course Objectives

  1. 1. Analyze common astronomical diagrams (e.g. HR diagram, Earth-Moon-Sun diagrams, EM
    spectra diagrams) to solve problems.
  2. 2. Explain how the relative positions of the Earth-Moon-Sun relate to the phases and rising and
    setting times of the Moon.
  3. 3. Explain the consequences of the tilt of Earth’s axis that combine to produce the seasons we
    observe on Earth and describe other planets (real and hypothetical) having different axial tilt
    or orbital properties that (would) result in seasonal characteristics different from those
    experienced on Earth.
  4. 4. Describe the overall structure of our Solar System and how the Nebular Hypothesis of Solar
    System formation accounts for similarities and differences between planets.
  5. 5. Apply scientific reasoning and mathematical calculations to solve problems involving
    continuous spectra and absorption and emission lines and evaluate the reasonableness of
    the results for different stars.
  6. 6. Compare and contrast different types of stars and explain the life cycle of stars using
    appropriate symbols, notation, and vocabulary.
  7. 7. Explain the dynamics of galaxies and galaxy clusters and relate this behavior to
    contemporary astronomical ideas (e.g. Big Bang, dark matter, dark energy).
  8. 8. Demonstrate increased attention to and appreciation of the patterns, organization, and
    vastness of the Universe exhibited in the night sky.
