Kepler Science Center The Kepler Science Center is a coordinating research and analysis organization focused on interpreting photometric time-series data from spaceborne observatories and supporting follow-up observations with ground-based facilities. Based in Pasadena and embedded within a network of NASA, university, and observatory partners, the center brings together teams from NASA Ames Research Center, NASA Goddard Space Flight Center, Jet Propulsion Laboratory, California Institute of Technology, and international institutes to advance exoplanet detection, stellar astrophysics, and time-domain astronomy. Its activities span pipeline development, community data releases, mission planning, and public engagement in collaboration with observatories and missions.

Overview

The center serves as a science operations hub interfacing with missions such as Kepler (spacecraft), K2 mission, Transiting Exoplanet Survey Satellite, Spitzer Space Telescope, Hubble Space Telescope, and future platforms including James Webb Space Telescope and Roman Space Telescope. It coordinates with survey facilities like Palomar Observatory, Lick Observatory, Mauna Kea Observatories, Subaru Telescope, and Very Large Telescope to validate planet candidates and support follow-up spectroscopy with instruments on Keck Observatory and Gemini Observatory. Cross-disciplinary linkages extend to the European Space Agency, Space Telescope Science Institute, Harvard-Smithsonian Center for Astrophysics, Massachusetts Institute of Technology, and major data centers.

History and Mission

Founded in the wake of the Kepler (spacecraft) launch and subsequent mission operations, the center built on heritage from teams at NASA Ames Research Center and SETI Institute that curated transit-search algorithms and vetting procedures. The mission statement emphasizes delivering vetted catalogs of planet candidates, enabling statistical studies for programs like the Exoplanet Exploration Program and informing proposals to agencies such as National Science Foundation and European Research Council. The institution’s charter connects to archival stewardship practices promoted by NASA/IPAC, Mikulski Archive for Space Telescopes, and international data policy frameworks adopted by Committee on Data (CODATA) and scientific consortia.

Facilities and Instrumentation

Laboratory and computational facilities include high-performance clusters linked to resources at NASA Advanced Supercomputing Division, cloud platforms used by Amazon Web Services and Google Cloud Platform under research agreements, and specialized hardware for photometric calibration developed with partners from Ball Aerospace and Northrop Grumman. Instrumentation partnerships support follow-up with spectrographs such as HIRES (Keck), HARPS-N, NIRSPEC, and multi-object facilities like Sloan Digital Sky Survey. Ground-based networks for time-domain monitoring involve collaborations with Las Cumbres Observatory and robotic telescope programs at Kitt Peak National Observatory.

Research Programs and Projects

Science programs span transit detection pipelines, stellar variability characterization, asteroseismology, false-positive discrimination, and statistical occurrence-rate studies. Major projects include catalog releases analogous to the Kepler Object of Interest lists, machine-learning vetting inspired by work at Stanford University and Carnegie Institution for Science, and synergies with citizen-science initiatives such as Planet Hunters and the Zooniverse platform. The center contributes to missions’ science working groups, participates in proposal-led campaigns for facilities like ALMA, and supports targeted campaigns on NGTS and TESS for bright-star characterization.

Data Management and Archives

Data stewardship practices align with archival standards from NASA Earthdata, IPAC, and the Space Telescope Science Institute by providing calibrated light curves, target pixel files, and derived products. The center maintains mirrored archives interoperable with the Virtual Observatory protocols and provides APIs and tools used by the Astrophysics Data System community. Data release policies accommodate embargo periods consistent with agreements from funding agencies such as NASA and the National Science Foundation, and the center supports reproducible research through containerized workflows using technologies championed by Carnegie Mellon University and open-source projects hosted on platforms like GitHub.

Education and Public Outreach

The center runs education programs in partnership with institutions including Smithsonian Institution, Planetary Society, SETI Institute, and university outreach offices at University of California, Berkeley and University of Cambridge. Public-facing activities include interactive visualizations, teacher resources aligned with standards promoted by National Science Teaching Association, and community science platforms like Zooniverse that engage amateur astronomers via projects modeled after Planet Hunters. The center also coordinates public seminars with media partners such as NPR and BBC Science to communicate discoveries and mission milestones.

Collaborations and Partnerships

Collaborative networks encompass federal agencies NASA Ames Research Center, NASA Goddard Space Flight Center, and National Science Foundation funding programs; academic partners including Harvard University, Princeton University, University of Oxford, University of Toronto, and ETH Zurich; observatories such as Keck Observatory, Gemini Observatory, European Southern Observatory; and industrial partners in aerospace and computing. International collaborations extend to European Space Agency, Canadian Space Agency, Japan Aerospace Exploration Agency, and consortia behind missions like PLATO (spacecraft) and ground projects including Large Synoptic Survey Telescope.
