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.

  • NuSTAR Users Commitee: Call for Self Nominations (18 Oct 2017)
    NASA's Nuclear Spectroscopic Telescope Array (NuSTAR) high-energy mission announces the creation of the NuSTAR Users Committee (NUC). The NUC will provide community advice and feedback to the project, to ensure that the interests of the guest investigator community are well-served by the project. Membership on this committee is open to the world, and we intend a committee that is diverse in terms of career stage, gender, and scientific focus. Letters of self-nomination to serve on this committee are due by November 3rd, 2017.

  • NASA Missions Catch First Light from a Gravitational-Wave Event (16 Oct 2017)
    Shortly after 8:41am EDT on Aug. 17, 2 seconds after LIGO and VIRGO detected a gravitational wave event, the Fermi Gamma-ray Space Telescope picked up a pulse of high-energy light from a powerful explosion, which was immediately reported to astronomers around the globe as a short gamma-ray burst. The Swift, Hubble, Chandra and Spitzer missions, along with dozens of ground-based observatories, including the NASA-funded Pan-STARRS survey, observed over the next few days and weeks the fading glow of the expanding debris from this blast, now believed to be a "kilonova".
  • First Detection of Gravitational waves from a Binary Neutron Star Inspiral on August 17, 2017 at 8:41am EDT (16 Oct 2017)
    The LIGO Scientific and Virgo collaborations report the first joint detection of a gravitational wave signal from a binary neutron star system, dubbed GW 170817. The gravitational waves were emitted during the final moments of the merger of two neutron stars with masses of about 1.6 and 1.1 times the mass of the sun and located about 130 million light-years away. 1.7 seconds later the Fermi GBM detected a short gamma-ray burst (GRB 170817A), and follow-up multi-wavelength observations pinpointed the counterpart object to be a kilonova (an r-process supernova) in the elliptical galaxy NGC 4993. The discovery paper has just appeared in the Phys Rev Letters, v. 119, 161101 (2017).
