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 not only data obtained by high-energy astronomy missions observing in the extreme-ultraviolet (EUV), X-ray, and gamma-ray bands, but also data from space missions, balloons, and ground-based facilities that have studied the relic cosmic microwave background (CMB).

  • NASA's Swift Mission Observes Mega Flares from a Mini Star (01 Oct 2014)
    On April 23, NASA's Swift satellite detected the strongest, hottest, and longest-lasting sequence of stellar flares ever seen from a nearby red dwarf star. The initial blast from this record-setting series of explosions was as much as 10,000 times more powerful than the largest solar flare ever recorded.
  • Swift Cycle 11 GI Program (30 Sep 2014)
    NASA received 165 proposals, requesting a total observing time of 14.1 Ms and $5.3M in funds for 1,044 targets. Considering PIs and Co-Is, about 500 individual scientists responded to the Swift Cycle 11 call. The Swift Cycle 11 Peer Review will be held in December to evaluate the merits of submitted proposals. Results will be posted in late December 2014.
  • Catalog of Swift XRT Counterparts to Unidentified 1FGL Sources (26 Sep 2014)
    This catalog listing 267 X-ray sources found in the Swift XRT FoV in observations of 134 high-latitude unidentified Fermi gamma-ray sources (from Takeuchi et al. 2013, ApJS, 208, 25) is now available in Browse and Xamin.
  • NICER Passes Critical Design Review (19 Sep 2014)
    NICER unanimously passed its CDR "with flying colors".
  • Milky Way Star Clusters (MWSC) Catalog (18 Sep 2014)
    This catalog listing the properties of the 3,000+ open clusters in the Galaxy has been updated to include 139 newly discovered clusters from Schmeja et al. 2014, A&A, 568, A51. The new version of MWSC is now available in Browse and Xamin.
  • NuSTAR CALDB Update (17 Sep 2014)
    The NuSTAR CALibration DataBase was updated on September 17, 2014 (CALDB version 20140917). This updates the NuSTAR clock correction file to version 39, valid up to 2014-09-17.
