World’s most decorated researchers in space science


Our Department of Astronomy & Astrophysics designs many of the world’s most powerful space technologies and telescopes. Our invention of segmented mirror technology shattered previous limits on telescope size and is said to have had “the biggest impact in optics after Newton.” Our scientists developed the laser guide star technology for adaptive optics (taking the twinkle out of the stars), and designed the Fermi Gamma-ray Space Telescope, the Automated Planet Finder at Lick Observatory, the Sloan Digital Sky Survey photometric camera, and the Keck Telescopes in Hawaii.
Oh, and we determined how to fix the flawed optics on the Hubble Space Telescope and were a leading partner in the NASA explorations using the Kepler planet-finding telescope and the Cassini mission to Saturn. The list goes on…

Career advancement

Astronomy is a relatively small field in the “industry of science,” making it extremely competitive to land permanent research or teaching positions. We’ve got you covered. The most telling success metrics for our astronomy program is the quality of the graduate students we attract and—more importantly—the professional success they achieve after they graduate. An Astronomy & Astrophysics Ph.D. at UC Santa Cruz is proven to give you:

  • A star-studded research network
  • Mentorship by internationally distinguished faculty and researchers
  • The latest high-impact research and instrumentation knowledge
  • Large project management and leadership skills
  • Intimate involvement with large international research projects, both government and private
  • Next-level teaching and science communications skills
  • A noticeable professional edge over your competition
  • Minimal debt

Leadership training

Our Department of Astronomy & Astrophysics offers many fellowship and leadership building opportunities. One of our most empowering programs is the Donald & Irene Osterbrock Leadership Program, which provides you with unique training, events, and grant opportunities to boost leadership and large project management skills.

Funding opportunity

In addition to being highly employable, you’ll leave UC Santa Cruz with minimal debt. 100 percent of our Astronomy & Astrophysics Ph.D. students receive tuition and/or stipend support, with an average of $50,300 in total support (data as of 2018). We strongly encourage and support all our graduate students in the process of securing independent research funding. As a result, our students receive many distinguished awards, honors, and accolades.
