BS Astronomy

Cornell University's BS in Astronomy is an outstanding choice if you want to explore the universe using real telescopes, advanced data analysis, and work alongside world-class researchers. You’ll join a program with a rich history of space exploration, deep connections to NASA missions, and a commitment to hands-on learning that sets you up for both graduate study and diverse careers.

Here’s how experiential learning comes to life for Astronomy majors at Cornell:

• Observational Astronomy Labs: Courses like ASTRO 1195 and ASTRO 4410 offer hands-on training with the Fuertes Observatory’s 12" telescope, Meade 8" telescopes, and the Hartung-Boothroyd Observatory’s 24-inch optical telescope, plus a 3.8-meter radio telescope. You’ll learn real observational techniques, CCD imaging, optical photometry, spectroscopy, and radio astronomy.

• Advanced Instrumentation & Data Analysis: In upper-level labs, you’ll use professional equipment and software for data collection, analysis, and research on celestial objects ranging from asteroids to galaxies. You’ll practice statistical data analysis, artefact excision, Fourier transforms, and software-defined radio skills essential for modern astronomy.

• Research Opportunities: Participate in the NSF-funded Research Experiences for Undergraduates (REU) program, where you’ll work on individual projects with Cornell faculty and research staff in areas like planetary science, exoplanets, instrumentation, cosmology, and more. Many students present their work at national conferences and may even contribute to published research.

• Spacecraft Planetary Image Facility (SPIF): Access a unique repository of spacecraft data for research and coursework, connecting you directly to real planetary exploration missions.

• Astronomy Club & Public Outreach: Join the Cornell Astronomy Club for regular observing and astrophotography sessions at Fuertes Observatory, and participate in public viewing nights and educational outreach, building your communication and teamwork skills.

• Flexible Program Structure: Choose between an Astrophysics Concentration (ideal if you’re aiming for graduate school or research) and a General Astronomy Concentration (for broader interests, including education and science communication). You can also pursue minors in Astrobiology or Data Science in Astronomy to further tailor your experience.

• Independent Study: Take on individual research projects (ASTRO 4940) under faculty guidance, allowing you to dive deep into topics that excite you most.

• Cutting-Edge Collaborations: Work with faculty involved in major NASA missions and international observatory projects, gaining exposure to the latest discoveries and instrumentation.

Cornell University’s BS in Astronomy prepares students for a wide range of careers and graduate programs through a rigorous foundation in astronomy, physics, and data analysis. Graduates are highly employable, moving into roles such as research scientist, software engineer, data analyst, science educator, lab technician, and technical specialist in observatories, technology, biotech, education, and public outreach. Many alumni also pursue graduate studies (MSc) in astronomy, astrophysics, planetary science, or related fields at top institutions worldwide.

Here’s how Cornell specifically supports your future:

• Career Services: Astronomy majors receive rigorous training in physics, mathematics, and astronomy, with core courses covering stars, galaxies, cosmology, planetary systems, and experimental/data analysis. Students engage in hands-on laboratory courses and have extensive opportunities for undergraduate research, especially in their junior and senior years, working alongside faculty on projects in astrobiology, planetary science, exoplanets, cosmology, gravitational waves, radio astronomy, and more. Many participate in the summer Research Experiences for Undergraduates (REU) program, collaborating on cutting-edge research topics and gaining valuable mentorship.

• Industry Partnerships: Cornell’s Department of Astronomy is deeply involved in major NASA missions (including the Mars Rovers) and collaborates with Cornell Engineering on space technology, satellite systems, robotics, and New Space industry initiatives. The department’s strong research culture and partnerships with organisations such as NASA, the Jet Propulsion Laboratory, and commercial space companies provide students with access to internships, collaborative projects, and industry networking.

• Employment Stats: Astronomy graduates from Cornell have entered diverse sectors, including technology, biotech, pharmaceuticals, and education. Recent employers include NASA (intern), MRV Systems (software engineer), California Institute of Technology (science educator), and Cornell University (lab technician). Many pursue advanced degrees at prestigious institutions such as Caltech, MIT, the University of Chicago, and UCLA. According to recent surveys, about half of physics/astronomy graduates pursue further education, while half enter the workforce directly, with strong placement in both academia and industry.

• Accreditation: The BS in Astronomy at Cornell is fully recognised in the US and internationally, and fulfils prerequisites for graduate and professional programs in science, engineering, and education.

• Graduate Outcomes: Students graduate with advanced analytical, quantitative, programming, and scientific communication skills, as well as hands-on experience in research and laboratory work. The program’s flexibility allows for concentrations in Astrophysics (for those pursuing research careers) or General Astronomy (for broader career interests, including education and outreach).

Further Academic Progression: After your BS in Astronomy at Cornell, you can pursue a master’s in astronomy, astrophysics, planetary science, or related fields at leading universities. The program also prepares you for professional roles in research, technology, education, and science communication, supported by Cornell’s strong research environment, faculty mentorship, and global reputation.
