About
At UC Santa Cruz, we’re exploring the universe and preparing the next generation of scientific explorers.
We are focused in three centers of discovery:
- Theoretical Astrophysics Santa Cruz (TASC). A true interdisciplinary approach to scientific computation and the visualization of the universe. With the use of supercomputers we test complex theories of our dynamic universe. Our partners include the UC Santa Cruz Digital Arts and New Media Center.
- Other Worlds Laboratory (OWL). A comprehensive research effort to find and understand planets around other stars and explore the diversity of our own solar system. Through new observations and sophisticated computer modeling we strive to understand how planets form and evolve over time and whether life exists on worlds beyond the Earth.
- Institute for Astronomical Instrumentation Research. Harnessing our expertise in developing the new technologies that will form the foundation for the world’s largest telescopes and other instruments.
Academics
The department offers both undergraduate and graduate degrees. Ph.D. graduates often obtain postdoctoral positions at research institutions and continue on in academia. Undergraduate majors often enter the K-12 teaching workforce as well as begin graduate studies at top Ph.D. programs in the U.S. Explore our undergraduate and graduate program options.

Diversity, Equity, & Inclusion

BLACK LIVES MATTER
We, the faculty, students, and staff of the UCSC Department of Astronomy & Astrophysics condemn racism, injustice, and hate. The unconscionable murders of Geoge Floyd, Breonna Taylor, Tony McDade, Ahmaud Arbery and countless other innocent Black lives at the hands of police is evidence of systemic racism and deeply-rooted social injustice that must be addressed. We mourn with our Black colleagues and students who are reminded of the marginalization and oppression that is still, today, a part of their experience. We acknowledge and deeply lament the undue burden and collective trauma that they carry.

We call for policy changes at all levels of policing that can immediately be implemented to reduce harm caused by police. We also support transformative change that moves beyond policing toward comprehensive structures for community safety. We urge campus administrators to audit campus police funding and resource allocations with such changes in mind. We condemn the unnecessary use of police force as was seen in the February 2020 graduate student strikes and hold these events as additional evidence that change is required.
We recognize that systemic racism is endemic to academia. This is evidenced in the under-representation of BIPOC (Black, Indigenous, and Persons of Color) faculty, especially in STEM fields. This is evidenced in the absence of Black faculty in our own department. We hear the voices of Black colleagues and students across the nation and at home describing their experiences of persistent microaggressions, macroaggressions, and structural biases that perpetuate and institutionalize exclusion.
We affirm a commitment to anti-racist practices that ensure every present and future member of our community feels valued and knows they belong. We pledge to take a critical look at hiring and graduate student admissions processes. We pledge to educate ourselves with regards to racism and to learn how to be active allies. We will critically examine the metrics we use to measure academic and professional success and better understand how they racially discriminate. We will identify the ways that important contributions to our science by persons of color have gone unnoticed. We pledge to update the department website by October 1, 2020 to report back on these activities.
This list is by no means exhaustive, nor is it sufficient. Rather, it represents a work in progress and our continuing pledge to do better.
