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.

  • XMM-Newton SAS v15.0.0 Released (05 Feb 2016)
    The latest release of the XMM-Newton Science Analysis Software.
  • Pictor A: Blast from Black Hole in a Galaxy Far, Far Away (02 Feb 2016)
    To obtain images of the jet from the central super-massive black hole in the active galaxy Pictor A, Hardcastle et al. (2016, MNRAS, in press) used NASA's Chandra X-ray Observatory at various times over 15 years. Chandra's X-ray data have been combined with radio data from the Australia Telescope Compact Array to allow a detailed study of the spatial, temporal and spectral properties of the AGN, jet, hotspot and lobes.
  • Swift CALDB Data updated (31 Jan 2016)
    A new makefilter parameter file for the Swift XRT has been added to the Swift XRT Caldb (update version 20160121) ...
  • INTEGRAL X-Rays Earth's Aurora (26 Jan 2016)
    Normally busy with observing high-energy black holes, supernovae and neutron stars, ESA's INTEGRAL space observatory recently had the chance to look back at our own planet's aurora. INTEGRAL detected high-energy auroral X-rays on 10 November 2015 as it turned to Earth, although it was looking for something else at the time, namely the diffuse cosmic X-ray background (CXB). On this occasion, the X-rays from Earth's aurora drowned out the CXB, providing exciting serendipitous science.
  • LISA Pathfinder Arrives at its "Worksite", the Sun-Earth L1 Point (22 Jan 2016)
    After a six-week journey, LISA Pathfinder (LPF) arrived at its destination today, an orbit around the Sun-Earth first libration point (L1), where it will soon start testing technologies crucial for exploring the gravitational Universe. LPF will test the key elements that could be used by a future mission to detect gravitational waves.
