Exploring the Frontiers of the Universe

Groundbreaking research, cutting-edge technology, award-winning faculty – UCLA’s Division of Astronomy & Astrophysics offers a rewarding environment to pursue higher education and topical research. All members of the Division carry out active research programs that garner widespread international recognition. Doctoral students can participate in a variety of research projects, which frequently incorporate observations with the world’s largest ground-based telescopes, orbiting observatories, and other astronomical facilities.
Our PhD recipients go on to highly productive careers in academia, government, industry and business. Many have obtained prestigious postdoctoral fellowships from entities such as the National Research Council, Hubble, NSF, Caltech Millikan, and Princeton Russell. UCLA faculty have access to numerous observational facilities, including the 10-m telescopes of the W. M. Keck Observatory in Hawaii, and the Division has strong bonds with Physics, and with Earth, Planetary and Space Science.
