Astronomy, the oldest of all scientific studies, has played a vital role in the development of modern science. Astronomers study the formation, composition, and evolution of various objects, such as planets, stars, galaxies, nebulae, black holes, and the Universe itself. Students take astronomy courses to prepare for a major in astronomy or to fulfill general education requirements. Graduates with a bachelor's degree in astronomy pursue careers as museum and planetarium directors, astronomers/astrophysicists, space scientists, mission data analysts, spacecraft and instrument designers, teachers, observatory technicians, telescope operators, optics or electronics technicians, computer programmers, and mathematicians.

ASTR 101: Descriptive Astronomy
Acceptable for Credit: CSU, UC Credit limitation
Lecture 3 hours. (1911.00)
This introductory course surveys the entire Universe while emphasizing the nature and process of physical science. Topics include the Earth-Sun-Moon system and night sky; Newton's laws of motion and gravitation; historical astronomy; electromagnetic radiation; spectroscopy; optics and telescopes; the formation and evolution of stars, planets, nebulae, galaxies, and the Universe as a whole; the Big Bang; and astrobiology. UC CREDIT LIMITATION: No credit if taken after ASTR 201.
ASTR 101L: Descriptive Astronomy Laboratory
This course provides a hands-on introduction to the methods and techniques of observational astronomy and data/error analysis. It emphasizes the collection, presentation, and interpretation of astronomical observations. Students learn to use a planisphere, read star charts, and operate small telescopes. Through indoor activities and by making naked-eye, binocular, and telescopic observations, students explore such topics as seasons, lunar phases, rotation of the Earth, optics, light and spectroscopy, planets, stars, galaxies, and cosmology.
ASTR 120: Life in the Universe
Acceptable for Credit: CSU, UC
Lecture 3 hours. (1911.00)
This introductory course surveys the study for life in the universe from the Big Bang to implications of contact with an extraterrestrial civilization while emphasizing the nature and process of physical science. Topics include the formation and evolution of the universe; origin, evolution, and nature of life on Earth; the definitions of “life” and “habitability”; potential in our solar system and beyond; methods of interstellar communication and travel; implications of contact; science vs. pseudoscience; and the status of the search to-date.
ASTR 201: Introductory Astronomy
This introductory course surveys the entire Universe with an emphasis on analytical, mathematical, and problem-solving skills. Topics include celestial mechanics, electromagnetic radiation and atomic physics, relativity, stellar structure and evolution, black holes, formation and evolution of planetary systems, galaxies, and cosmology. The course is directed towards students with a strong preparation and interest in science and mathematics.
ASTR 292: Internship Studies
Corequisite: Complete 75 hrs paid or 60 hrs non-paid work per unit.
Enrollment Limitation: Instructor, dept chair, and Career Center approval. May not enroll in any combination of cooperative work experience and/or internship studies concurrently.
Acceptable for Credit: CSU
This course provides students the opportunity to apply the theories and techniques of their discipline in an internship position in a professional setting under the instruction of a faculty-mentor and site supervisor. It introduces students to aspects of the roles and responsibilities of professionals employed in the field of study. Topics include goal-setting, employability skills development, and examination of the world of work as it relates to the student's career plans. Students must develop new learning objectives and/or intern at a new site upon each repetition. Students may not earn more than 16 units in any combination of cooperative work experience (general or occupational) and/or internship studies during community college attendance.
