The Department of Astronomy offers graduate programs leading to the Master of Science and Doctor of Philosophy degrees. The goal of the graduate program in astronomy is to provide broadly based training in modern astrophysics and astronomy for a small and carefully selected student body. Individually designed programs involving close contact with faculty members are encouraged, and an understanding of fundamental principles and techniques and their applications to research problems of current interest is emphasized. Students are expected to acquire a solid knowledge of modem physics as well as of general astronomy. A major objective is to maintain an exciting intellectual environment in which students can develop their scientific creativity and their enthusiasm for astronomy.

Graduate Degree Programs in Astronomy

Astronomy, MS

Astronomy, PhD

optional concentration: Astrochemistry


Admission to the astronomy graduate program requires an outstanding record of accomplishment and clear evidence of considerable academic promise, as judged by test scores, resume (or c.v.), letters of recommendation, personal statement, and strong intellectual achievements.  A bachelor's degree or its equivalent in astronomy, physics, chemistry, mathematics, or another related technical field from an accredited college or university in the U.S. or an approved institution of higher learning abroad is required for admission.

A minimum grade point average of 3.0 (A = 4.0) and satisfactory scores on the Graduate Record Examination (GRE) (verbal, quantitative, and advanced physics portions) are required for admission. Course preparation in intermediate and advanced undergraduate physics and astronomy are essential. Students are expected to make up deficiencies during the first graduate year.

All applicants whose native language is not English are required to submit the results of the TOEFL or IELTS as evidence of English proficiency, as required by Graduate College policy. More information on the English Proficiency Requirement can be found at the Graduate College Admissions Web site.

Admission decisions are normally made once a year in the spring.  Applications for admission and financial assistance must be received by January 15.  In rare circumstances, applicants may be admitted for the spring semester, in addition to the customary fall semester admissions.

See the Astronomy graduate admissions Web site ( for more information and application materials.

Graduate Teaching Experience

Although teaching is not a general Graduate College requirement, experience in teaching is considered an important part of the graduate experience in this program.

Faculty Research Interests

Research activity in the Department of Astronomy includes observational and theoretical investigations of a wide array of astronomical objects:

  • Early-universe cosmology (inflation, particle dark matter, cosmic nucleosynthesis)
  • Large-scale structure of the universe (cosmic microwave background, galaxy clusters)
  • Extragalactic systems (galaxy structure and evolution, interacting galaxies, active galaxies, jets, and quasars)
  • Interstellar medium (multiple phases, molecular clouds, HII regions, bubbles and superbubbles, planetary nebulae, supernova remnants, magnetic fields, and galactic structure)
  • Stars (formation, structure and evolution, atmospheres, nucleosynthesis, novae, supernovae, pulsars, and stellar statistics)
  • Compact objects (black holes, neutron stars, white dwarfs)

Theoretical astrophysics is also a strong research interest many faculty members in the Department of Astronomy and the Department of Physics. Current activity centers on:

  • Astrophysical fluid dynamics, magnetohydrodynamics and radiation hydrodynamics
  • Physics of dense stellar matter
  • Accretion phenomena
  • High energy and relativistic astrophysics
  • Cosmic inflation and structure formation
  • Nuclear and particle processes in cosmology and astrophysics
  • Black hole physics and astrophysics
  • Gravitational lensing
  • Gravitational wave phenomena

Facilities and Resources

  • The Dark Energy Survey
  • The Large Synoptic Survey Telescope
  • The South Pole Telescope
  • Astronomy students and faculty successfully compete for time on national facilities.  These include ground-based telescopes of the National Radio Astronomy Observatory, such as the Atacama Large Millimeter Telescope and the Very Large Array, and the National Optical Astronomy Observatory telescopes.  Illinois research involves many space-based telescopes, including the Hubble, Planck, Spitzer, Herschel, Chandra, and Fermi.
  • A number of projects in the Department of Astronomy partner with the National Center for Supercomputing Applications (NCSA) at Illinois. This includes development and application of astrophysical simulations such as the FLASH package and general relativistic magnetohydrodynamic codes that provide insight into the nature of structure formation and the physics of black holes.  Astronomy faculty also leverage NCSA's pioneering development of cyberinfrastructure environments to facilitate data transport for the Sloan Digital Sky Survey (SDSS), the Dark Energy Survey, the Square Kilometer Array, and the Large Synoptic Survey Telescope.  NCSA and the Astronomy Department also jointly founded the Laboratory for Cosmological Data Mining to apply novel algorithms to the rich datasets now available for cosmological analysis, including those from the SDSS and Wilkinson Microwave Anisotropy Probe.
  • Illinois is the home of the Blue Waters National Petascale Computing Facility, one of the most powerful supercomputers in the world, and the most powerful on a university campus.  A portion of Blue Waters time is dedicated to Illinois faculty, and Astronomy students and faculty use Blue Waters for their research.

Financial Aid

University fellowships are available and may be combined with part-time teaching assistantships. Most resident students are supported for their first two or three years by half-time teaching assistantships. The typical teaching assistant takes two or three graduate courses per semester and spends twenty hours per week handling quiz sections in elementary astronomy courses. Teaching assistantships are responsible positions, and the concomitant duties are considered to be a valuable part of the student’s educational experience. Advanced students may compete for research assistantships offered by faculty members whose research is partially supported by federal grants.
