The High Energy Astrophysics Science Archive Research Center (HEASARC) is the primary archive for NASA's (and other space agencies') missions studying electromagnetic radiation from extremely energetic cosmic phenomena ranging from black holes to the Big Bang. Since its merger with the Legacy Archive for Microwave Background Data Analysis (LAMBDA) in 2008, the HEASARC archive contains data obtained by high-energy astronomy missions observing in the extreme-ultraviolet (EUV), X-ray, and gamma-ray bands, as well as data from space missions, balloons, and ground-based facilities that have studied the relic cosmic microwave background (CMB) radiation in the sub-mm, mm and cm bands.

The HEASARC is a member of the NASA Astronomical Virtual Observatories (NAVO) where we work with other NASA archives to ensure comprehensive and consistent VO access to NASA mission datasets. Users may now query the HEASARC's catalogs using VO-enabled services and specialized tools. This page describes how to get to the HEASARC VO-enabled services and provides information on other HEASARC VO activities.

Try ROSAT 3c273 1d to get ROSAT data within one degree of 3C273 or chanmaster bii>80 status='archived' to get archived Chandra observation data near the north galactic pole.

Note: For more than one target or when using any qualifier other than a mission, use quotes around targets that have embedded white space.(e.g., 'ar lac').

  • ISS-CREAM for the International Space Station (14 Aug 2017)
    At 12:31 pm EDT today (August 14), a SpaceX Dragon spacecraft was launched from Kennedy Space Center carrying, among many other things, the ISS-CREAM (International Space Station Cosmic Ray Energetics And Mass) payload. This will be attached to the International Space Station and, starting in Fall 2017, will be used to to extend the energy reach of direct measurements of cosmic rays to the highest energy possible to probe their origin, acceleration and propagation. ISS-CREAM is a collaboration of US, Korean, French and Mexican institutions.
  • The S-Band Polarization All-Sky Survey (S-PASS) 2.3-GHz Source Catalog (11 Aug 2017)
    This new catalog of 23,389 2.3-GHz sources detected by the Parkes radio telescope in the entire southern sky except for regions within 10 degrees of the Galactic Plane (from Meyers et al. 2017, PASA, 34, 13) is now available in Browse and Xamin.
  • NASA Selects Proposals to Study Galaxies, Stars, Planets (10 Aug 2017)
    NASA has selected 6 astrophysics Explorers Program proposals for concept studies. The selected proposals comprise 3 Medium-Class Explorers missions and 3 Explorers Missions of Opportunity, and include Arcus, a MidEx mission that would study stars, galaxies and clusters of galaxies using high-resolution X-ray spectroscopy, the Transient Astrophysics Observer on the ISS MoO, a wide-field X-ray transient detector that would observe numerous such events per year related to compact objects, e.g., GW counterparts, X-ray bursts, GRBs, etc., and the Compton Spectrometer and Imager Explorer (COSI-X), a balloon-borne, wide-FOV telescope designed to survey the gamma-ray sky at 0.2-5 MeV, performing high-resolution spectroscopy, wide-field imaging, and polarization measurements.
