Learn about planetary astronomy, stellar astrophysics, cosmology and the origins of the universe with opportunities for hands-on research and collaboration.

Astronomy, offered via three Physics Major tracks in the Physics and Astronomy Department and in collaboration with Harvey Mudd College, gives students tools to explore the universe.

Our unparalleled facilities include a mountain-top one-meter telescope, an on-campus observatory, a digital planetarium and an adaptive optics research laboratory.

You’ll have opportunities to do research on campus and at top astronomy facilities such as Caltech and the Carnegie observatories.

Majors earn a B.A. in physics with an astronomy, astrophysics, or Earth, planetary and space sciences track. A minor is also available.

A thesis is required and independent research encouraged, usually in conjunction with faculty research. Recent projects include monitoring active galactic nuclei, quasar absorption line spectroscopy and telescope instrument design.

    Adam Mitchell '18 observed nine near-earth asteroids in order to analyze and determine their specific orbits and took blind surveys of the sky to potentially discover new near-earth asteroids. These faint asteroids are roughly one thousand trillion times fainter than a full moon.

One of the great things about studying astronomy is the diversity of skills you can develop. Creativity in constructing software, a firm understanding of the physical principles at hand, and the ability to communicate complex ideas succinctly are all very important for success in this field!

Faculty & Teaching

The astronomy faculty—with expertise in astrophysics, archeoastronomy, star formation, the physics of active galactic nuclei, gravitational waves, the infrared properties of galaxies, x-ray astronomy and optic systems—frequently involves students in their research projects.

Prof. Bryan Penprase

What distinguishes our Physics and Astronomy programs is the incredible access that students have to facilities that include a one-meter telescope in the San Gabriel Mountains, a scanning electron microscope and other advanced equipment, entirely dedicated to undergraduate research and study. Pomona is also home to many new and innovative instruments our students have helped design and build, most recently our new adaptive optics instrument.
