Astronomy major

Astronomy: courses, careers, and where to study

Astronomy studies the physics of planets, stars, galaxies, and the universe, suiting students who pair strong math and physics with observational and computational analysis.

An Astronomy major is usually a bachelor's degree built on a physics core, classical mechanics, electromagnetism, thermodynamics, and quantum mechanics, alongside calculus through differential equations and linear algebra. Astronomy-specific coursework covers stellar structure and evolution, planetary science, galactic and extragalactic astronomy, cosmology, and observational methods, including telescope use, detectors, spectroscopy, and data reduction. Many programs are offered as Astronomy, Astrophysics, or a Physics degree with an astronomy concentration, and most BS tracks require a senior research project.

Because of the heavy physics and computing content, graduates are well prepared for quantitative work in software, data science, engineering, instrumentation, and education, as well as graduate study. Research positions in astronomy, the path most associated with the title "astronomer," typically require a doctoral degree, and many graduates pursue a PhD before working at universities, observatories, or national laboratories.

The U.S. Bureau of Labor Statistics reports a 2024 median wage of $132,170 for astronomers and projects 2.2% employment growth for the occupation. Because the field is small, openings are limited and competition for research roles is high.

Academic classification (CIP)

In the federal Classification of Instructional Programs, Astronomy maps to CIP 40.0201, Astronomy, within the PHYSICAL SCIENCES family. The official definition:

A general program that focuses on the planetary, galactic, and stellar phenomena occurring in outer space. Includes instruction in celestial mechanics, cosmology, stellar physics, galactic evolution, quasars, stellar distribution and motion, interstellar medium, atomic and molecular constituents of astronomical phenomena, planetary science, solar system evolution, and specific methodologies such as optical astronomy, radioastronomy, and theoretical astronomy.

Before you commit to a Astronomy major

CampusPin does not rank programs. Use these prompts to pressure-test whether a specific Astronomy program fits your goals, they are decision questions, not claims about any school.

Ask the Astronomy department

  • Which concentrations or specializations are offered, and which faculty lead them?
  • What does the typical course sequence look like, and how much is required vs. elective?
  • What labs, studios, clinical placements, or research opportunities are available to undergraduates?
  • Is there a capstone, thesis, internship, or co-op requirement?

Ask current students & check the curriculum

  • How heavy is the workload, and how accessible is the faculty?
  • What internships or co-ops did you do, and where do recent graduates end up?
  • Does the required curriculum actually match the careers listed above?
  • How easy is it to add a minor, double major, or switch tracks later?
Accreditation & licensure: Most Astronomy programs are covered by their institution's regional accreditation; specialized programmatic accreditation is less common in this field. Confirm any field-specific accreditation or licensure that matters for your goals.
Degree level & graduate study: Many Astronomycareers are open with a bachelor's degree, but some, such as research, advanced-practice, or licensure-track roles, require a master's or doctorate. Check the typical entry-level education on each linked career page above before assuming a bachelor's is enough.
