This course deals with the objects and techniques of astronomical investigation. We will consider planets, stars, and galaxies, with regard to their physical nature, history, and interrelations. Its specific learning goals are that students will:

  • 1) be able to identify key concepts in the sciences to provide a broad perspective on the human condition.
  • 2) be able to recognize and explain the scientific method, and evaluate scientific information.
  • 3) be able to characterize the appearance and motion of celestial objects.
  • 4) be able to identify the key conceptual advances (and associated figures) in the history of astronomy.
  • 5) understand the relationship between light, matter, and energy in an astronomical context.
  • 6) understand the content, formation and evolution of planetary systems.
  • 7) understand the nature and evolution of stars.
  • 8) understand the nature and evolution of galaxies.
  • 9) understand the nature and evolution of the Universe.
