The High Energy Astrophysics Science Archive Research Center (HEASARC) is the primary archive for NASA's (and other space agencies') missions dealing with electromagnetic radiation from extremely energetic 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's holdings contain data obtained by NASA's high-energy astronomy missions observing in the extreme-ultraviolet (EUV), X-ray, and gamma-ray bands, as well as data from missions, balloons, and ground-based facilities that have studied the relic cosmic microwave background (CMB).

  • Swift CALDB Data updated (30 Jul 2014)
    The Swift Caldb has been updated for the SC (update version 20140718) and the XRT (update version 20140709)...
  • NASA's DXL Rocket Settles Interstellar Debate (29 Jul 2014)
    New findings (Galeazzi et al. 2014, Nature, in press; Snowden et al. 2014, ApJL, 791, L14) from the DXL (Diffuse X-ray emission from the Local Galaxy) mission have resolved a decades-old puzzle about a fog of low-energy X-rays observed over the entire sky. Astronomers have now confirmed the long-held suspicion that much of this glow stems from a region of million-degree interstellar plasma known as the local hot bubble.
  • NuSTAR CALDB Update (25 Jul 2014)
    The NuSTAR CALibration DataBase was updated on July 25, 2014 (CALDB version 20140715). This updates the NuSTAR clock correction file to version 37, valid up to 2014-07-15.
  • PIMMS updated to Version 4.7a (25 Jul 2014)
    Version 4.7a contains an updated post-launch effective area curve file for NuSTAR...
  • Viewing tool updated (22 Jul 2014)
    The Swift pole constraints have been updated in the Viewing tool. The revised coefficients extrapolate the trend for the next year. The web interface has also been enhanced with improved error handling.
  • NASA's Chandra X-ray Observatory Celebrates 15th Anniversary (22 Jul 2014)
    Fifteen years ago, the Chandra X-ray Observatory was launched into space aboard the Space Shuttle Columbia. Since its deployment on July 23, 1999, Chandra has helped revolutionize our understanding of the universe through its unrivaled X-ray vision. To celebrate its 15th anniversary, four new images of supernova remnants, the Crab Nebula, Tycho, G292.0+1.8, and 3C58 , are being released.
