Department of Astrophysical and Planetary Sciences is an academic unit specializing in the study of astronomy, astrophysics, and planetary science within a research university context, combining theoretical, observational, and experimental approaches to celestial phenomena. The department maintains connections to national laboratories, space agencies, and international observatories such as NASA, NOAA, European Space Agency, National Science Foundation, and Los Alamos National Laboratory to support graduate and undergraduate training in observational techniques, computational modeling, and instrument development.

History

The department traces origins to early 20th-century programs influenced by figures associated with Mount Wilson Observatory, Yerkes Observatory, Harvard College Observatory, Carnegie Institution for Science, and initiatives linked to Smithsonian Institution and United States Naval Observatory, with expansions following milestones like the launch of Sputnik and missions such as Mariner program, Voyager program, Apollo program, and Hubble Space Telescope. Growth accelerated through collaborations with institutions including Caltech, Massachusetts Institute of Technology, Princeton University, University of Chicago, and Stanford University, and through faculty recruited from sites such as Jet Propulsion Laboratory, European Southern Observatory, Kitt Peak National Observatory, and Sierra Nevada Observatory. Endowment gifts and federal awards from agencies like National Aeronautics and Space Administration and National Science Foundation paralleled mergers with related units inspired by advances from projects such as Kepler space telescope, Cassini–Huygens, Mars Reconnaissance Orbiter, and Chandra X-ray Observatory.

Academic Programs

Degree programs encompass undergraduate majors, master's degrees, and Ph.D. tracks integrating curricula influenced by texts and curricula used at Caltech, Princeton University, University of Cambridge, University of California, Berkeley, and University of Chicago, with courses referencing methods from Max Planck Institute for Astrophysics, CERN, Los Alamos National Laboratory, Argonne National Laboratory, and Lawrence Berkeley National Laboratory. Programs prepare students for careers at organizations including NASA Jet Propulsion Laboratory, European Space Agency, SpaceX, Blue Origin, Ball Aerospace, and Lockheed Martin, and for postdoctoral positions at centers like Institute for Advanced Study, Flatiron Institute, and Kavli Institute for Theoretical Physics. Cross-disciplinary options link to departments at School of Engineering and Applied Science, Department of Physics, Department of Geology, Department of Atmospheric and Oceanic Sciences, and partnerships with School of Medicine for instrumentation and data analysis training.

Research Areas

Active research spans observational cosmology informed by measurements from Planck (spacecraft), WMAP, Sloan Digital Sky Survey, and Large Synoptic Survey Telescope initiatives; exoplanet discovery and characterization leveraging techniques from Kepler space telescope, Transiting Exoplanet Survey Satellite, European Southern Observatory, and Gemini Observatory; planetary geophysics shaped by data from Mars Reconnaissance Orbiter, Mars Science Laboratory, Cassini–Huygens, and Venus Express; and high-energy astrophysics connected to Chandra X-ray Observatory, Fermi Gamma-ray Space Telescope, XMM-Newton, and INTEGRAL. Theoretical and computational studies draw on collaborations with Supercomputing Center, National Center for Atmospheric Research, Princeton Plasma Physics Laboratory, and institutes like Perimeter Institute, addressing problems related to black hole dynamics, galaxy formation, stellar evolution, magnetohydrodynamics, and astrochemistry.

Faculty and Staff

Faculty include observational astronomers, theoretical astrophysicists, planetary scientists, and instrument builders with backgrounds from institutions such as Harvard University, Yale University, Columbia University, University of California, Santa Cruz, and Brown University, and who have held positions at NASA Goddard Space Flight Center, National Radio Astronomy Observatory, Max Planck Society, and CNRS. Staff scientists and engineers often come from or collaborate with Jet Propulsion Laboratory, Ball Aerospace, Northrop Grumman, Aerospace Corporation, and technical partners at National Optical Astronomy Observatory. Graduate advisors have received honors tied to prizes like the Nobel Prize in Physics, Breakthrough Prize in Fundamental Physics, Gruber Foundation Prize, Bakerian Medal, and fellowships from National Science Foundation and Newton Fund.

Facilities and Observatories

On-campus facilities include teaching observatories modeled after Lick Observatory and instrument labs comparable to those at Space Telescope Science Institute, with radio, optical, and infrared capabilities linking to external arrays such as Atacama Large Millimeter Array, Very Large Array, Subaru Telescope, Keck Observatory, and Mount Graham International Observatory. Laboratory spaces support instrumentation and sample analysis with equipment comparable to Johnson Space Center facilities, and computational clusters tied to XSEDE, Oak Ridge Leadership Computing Facility, and cloud resources from Google Cloud and Amazon Web Services for large-scale simulations and data reduction.

Student Life and Outreach

Student organizations encompass chapters aligned with American Astronomical Society, Society of Physics Students, Planetary Society, Society for Industrial and Applied Mathematics, and Institute of Electrical and Electronics Engineers, offering seminars, journal clubs, and public engagement through partnerships with Smithsonian Astrophysical Observatory, Fiske Planetarium, Denver Museum of Nature & Science, and local K–12 STEM initiatives including collaborations with Boulder Valley School District, Teach for America, and National Science Teachers Association. Outreach programs coordinate observing nights, citizen science projects promoted by Zooniverse, and internship pipelines to agencies such as NASA Ames Research Center and NOAA.

Collaborations and Partnerships

The department maintains formal collaborations and consortia with NASA, European Space Agency, National Science Foundation, National Radio Astronomy Observatory, Max Planck Institute for Astronomy, Centre National de la Recherche Scientifique, University of Oxford, Imperial College London, University of Tokyo, University of Toronto, Australian National University, and industrial partners including SpaceX and Ball Aerospace to participate in missions, instrument development, and data analysis consortia linked to projects like James Webb Space Telescope, Europa Clipper, Nancy Grace Roman Space Telescope, and multinational survey initiatives.
