Astrophysics Data Centers
Astrophysics Archives for Mission Data
High Energy Astrophysics Science Archive Research Center (HEASARC)
The High Energy Astrophysics Science Archive Research Center (HEASARC) is the primary data archive for high-energy astrophysics missions in the extreme ultraviolet, X-ray and gamma-ray wavelengths, and includes the Chandra X-Ray Observatory archive.
The Legacy Archive for Microwave Background Data Analysis (LAMBDA) is part of NASA’s HEASARC. It is a multi-mission NASA center for cosmic microwave background (CMB) radiation research. It offers researchers archival data, software tools, and other sites of interest related to cosmological missions.
IPAC Infrared Science Archive (IRSA)
The IPAC InfraRed Science Archive (IRSA) contains the science products from NASA’s infrared and submillimeter projects, including Spitzer, WISE, IRAS and 2MASS. IRSA also provides data from several ESA missions that NASA participated in, including ISO, Planck, Herschel, and Euclid.
Mikulski Archive for Space Telescopes (MAST)
The Mikulski Archive for Space Telescopes (MAST) is a NASA-funded project to support and provide to the astronomical community a variety of astronomical data, with the primary focus on scientifically related datasets in the optical, ultraviolet, and near-infrared parts of the spectrum. It includes data from the Hubble, James Webb, and Nancy Grace Roman Space Telescopes.
Additional Astrophysics Data Systems
NASA Astrophysics Data System (ADS)
The Astrophysics Data System (ADS) is a digital library portal for researchers in astronomy and physics. The Smithsonian Astrophysical Observatory (SAO) at Harvard operates ADS for the scientific community under a NASA cooperative agreement. Per NASA request, ADS is expanding to include additional science domains like heliophysics, planetary science and Earth science under the Science Explorer (SciX) label.
NASA Exoplanet Archive (NEA)
The NASA Exoplanet Archive (NEA) is an on-line resource that compiles cross-referenced data on exoplanets and their host stars. It provides access to key datasets – such as stellar and planetary parameters, light curves, spectra, and radial velocity data – and offers tools for analyzing and visualizing this information to support exoplanet discovery and characterization. NEA is hosted at the NASA Exoplanet Science Institute (NExScI) which is the science operations and analysis center for NASA’s Exoplanet Exploration Program.
NASA/IPAC Extragalactic Database (NED)
The NASA/IPAC Extragalactic Database (NED) is an online astronomical database for astronomers funded by NASA. It collates and cross-correlates astronomical information on extragalactic objects, including cross-identification, accurate positions, redshifts and other physical parameters, images and spectra, and bibliographic references.
Set of Identifications, Measurements, and Bibliography for Astronomical Data (SIMBAD)
SIMBAD (Set of Identifications, Measurements and Bibliography for Astronomical Data) is a database of astronomical objects of interest beyond the Solar System: stars, galaxies, interstellar/intergalactic medium sources, clusters of stars/galaxies, exoplanets, gravitational sources, and transient events. It is operated by the Centre de données astronomiques de Strasbourg (CDS) in France. For each object, it provides its bibliography, fundamental parameters (astrometry, velocity/redshift, magnitudes, etc.) as well as a collection of additional measurements. A mirror copy of SIMBAD is maintained at the Smithsonian Astrophysical Observatory (SAO) at Harvard.
