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.

  • Record-Breaking Galaxy Cluster Discovered (30 Aug 2016)
    A new record for the most distant galaxy cluster has been set using NASA's Chandra X-ray Observatory and other telescopes. This galaxy cluster called CL J1001+0220 may have been caught right after birth, a brief, but important stage of evolution never seen before. It is located about 11.1 billion light years from Earth. The discovery of this object pushes back the formation time of galaxy clusters by about 700 million years. A paper on these results has just appeared in ApJ and is available online here.
  • Fifth IBIS/ISGRI Soft Gamma-Ray Survey Catalog (30 Aug 2016)
    The fifth version of the IBIS/ISGRI source catalog containing the soft gamma-ray properties of 939 sources found in the first 1000 orbits (~3000 days) of INTEGRAL obsdervations (from Bird et al. 2016, ApJS, 223, 15) is now available in Browse and Xamin.
  • Chandra Deep Field North 2-Megasecond Improved Point Source Catalog (25 Aug 2016)
    This catalog containing the X-ray and multiwavelength properties of 755 X-ray sources found in a new analysis of the CDF-N Field 2-Ms data (from Xue et al. 2016, ApJS, 224, 15) is now available in Browse and Xamin.
  • XMM-Newton AO-16 Solicitation Released (23 Aug 2016)
    XMM-Newton observing proposals are solicited in response to the Fourteenth Announcement of Opportunity.
  • SkyView v3.2.0 Preview: Summary (18 Aug 2016)
    Next week we will be releasing version 3.2.0 of SkyView. You can play with it right now if you specify the version v3.2.0 in the SkyView URL, but it’s still being tested. There are several major changes in this release … Continue reading
  • A Black Hole Story Told by a Cosmic Blob and Bubble: The Mystery of Hanny's Voorwerp (10 Aug 2016)
    Two cosmic structures show evidence for a remarkable change in behavior of a supermassive black hole in a distant galaxy. Using data from the Chandra X-ray Observatory and other telescopes, Lia Sartori and colleagues are piecing together clues from a cosmic 'green blob' (dubbed Hanny's Voorwerp) and a gas bubble in the nearby galaxy IC 2497 that could be a new way to probe the past activity of a giant black hole and its effect on its host galaxy. A paper on these results recently appeared in MNRAS and is available online here.
