Department of Astronomy and Planetary Science

Your future is in the stars

Astronomy and Planetary Science ask some of the most exciting questions we can imagine like: how do planets form, could life exist elsewhere, what shapes galaxies, stars, and the worlds in our own solar system? 

A degree in Astronomy and Planetary Science can lead to a career in research, data analysis, aerospace, education, observatory operations, science communication, space mission support, and the rapidly growing private space industry. If you can picture yourself analyzing telescope data, modeling planetary surfaces, helping design instruments for space missions, or studying the chemistry of distant worlds, this degree path will help you turn that curiosity into discovery! 

Why study Astronomy and Planetary Science at NAU

Whether you’re taking your first astronomy course or diving into high-level research, you’ll find a department known for discovery and a community ready to support you in every step of your NAU journey.

As an undergraduate, you’ll set yourself up for a strong start by sharpening your math skills before you arrive—your placement will help determine your path forward. New students are also encouraged to join the first-year Learning Community, which connects you with peers and mentors through shared housing and activities. Arizona transfer students can use the state equivalency guide to see how their coursework aligns with NAU requirements.

At the graduate level, you’ll work directly with faculty leading research in topics like planetary surfaces, exoplanets, astrochemistry, and computational astrophysics. The program’s visibility and strong research collaborations make it a standout choice if you’re aiming for a career in academics or industry. 

Destination for discovery

Flagstaff is the world’s first International Dark Sky City and home to a long legacy of astronomical breakthroughs. It’s no surprise that students from across the country choose NAU for its unmatched setting, hands-on research opportunities, and reputation as a destination for discovery. 

More than half of the undergraduate students studying Astronomy and Planetary Science come from out of state, drawn by the opportunity to learn in a place where observation and exploration are part of the community’s identity. 

Unparalleled opportunities

You’ll be studying in a city where exploration is built into the landscape. Flagstaff’s proximity to world-renowned institutions like Lowell Observatory, the U.S. Geological Survey Astrogeology Science Center, Meteor Crater, and a growing network of space-tech companies means you’ll have access to internships, research opportunities, and collaborations you won’t find anywhere else.

Learning outcomes

As an Astronomy and Planetary Science major at NAU, you will:

• apply the laws of physics in order to understand the origin and evolution of the stars, galaxies, Solar System, and other planetary systems.
• take good data with increasingly sophisticated equipment in introductory, intermediate, and advanced physics laboratories.
• clearly communicate and defend work in verbal, written, and visual formats to scientific and non-scientific audiences.
• reduce and analyze data from a research grade telescope and a CCD imaging system using professional astronomical software.

Student clubs and organizations

Join communities of stargazers and explorers through student groups that make exploration and professional development fun and collaborative. 

Dedicated support

No one explores the universe alone. Here, you’ll find support systems that help you grow academically, professionally, and personally from your first semester. 

Faculty mentorship

You’ll build connections with faculty quickly through small classes and labs. Faculty of the Department of Astronomy and Planetary Science will know your goals, cheer you on, and help you find your place in the astronomy community.

Scholarships and assistantships

Many undergraduate and graduate students take on paid research positions or assistantships that help offset costs while gaining professional experience. These opportunities allow you to focus on your goals and contribute to meaningful work while reducing the burden of tuition costs. 

Launch your career with real experience

From your first year, you'll have opportunities to join faculty on active research projects, something that might be reserved for advanced students in other programs. Nearly half of undergraduates studying Astronomy and Planetary Science get hands-on experience with Flagstaff’s astronomy community working as telescope operators, tour guides, research assistants, and project collaborators. With strong scientific training, professional connections, and first-hand experience, you’ll graduate ready to launch a successful career.
