The Astronomy program introduces students to physical properties and processes that govern celestial bodies in the Universe.  Students may take astronomy courses to satisfy their natural sciences requirements or to transfer with a major in astronomy or double major in astronomy and physics to the university. 

Students who pursue a B.S. degree in astronomy will be qualified to enter a teaching credential program, operate a planetarium, and assist at an observatory.  With an M.S. degree, students can teach astronomy or physics at a community college, be a telescope operator at a major observatory, or work in industry.  A Ph.D. qualifies students for a career in research at a university, space agency, or observatory.

Astronomy courses include astronomical demonstrations and shows in the Hartnell College Planetarium


Upon successful completion of the Astronomy program, a student should be able to:

  • explain and discuss basic astronomical phenonmena.
  • apply the laws of physics to explain the properties of planets, stars, galaxies, and the Universe.
  • explain and discuss the impact and history of scientific theories and their importance in the advancement of astronomy.
  • demonstrate proficiency in applying scientific procedures for making observations and measurements typical of modern astronomical research.
