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.

  • Milky Way Star Clusters (MWSC) Catalog (01 Oct 2015)
    This catalog listing the properties of the 3,000+ open clusters in the Galaxy has been updated to include 63 newly discovered clusters from Scholz et al. 2015, A&A, 581, A39. The new version of MWSC is now available in Browse and Xamin.
  • Swift Cycle 12 GI Program (29 Sep 2015)
    NASA received 185 proposals, requesting a total observing time of 15.8 Ms and $6.0M in funds for 1,555 targets. Considering PIs and Co-Is, more than 600 individual scientists responded to the Swift Cycle 12 call. The Swift Cycle 12 Peer Review will be held in December to evaluate the merits of submitted proposals. The results of the Peer Review will be posted in late December 2015.
  • Astrosat, India's First Astronomy Satellite Launched into Space (28 Sep 2015)
    Astrosat, an Indian multi-wavelength observatory including 1 ultraviolet and 4 X-ray instruments, was successfully launched into space on a Polar Satellite Launch Vehicle today (Sep 28) at 04:30 GMT. Congratulations to all of our Indian colleagues and their international collaborators!
  • Sgr A*, Milky Way's Super-Massive Black Hole, Shows Signs of Increased Chatter (28 Sep 2015)
    3 orbiting X-ray space telescopes (Swift, Chandra and XMM-Newton) have detected an increased rate of X-ray flaring from Sgr A*, the usually quiet giant black hole at the center of our galaxy, in the last year compared to the previous 14 years of long-term monitoring. In a recently accepted paper, Ponti et al. (2015, MNRAS, in press) discuss whether this is normal behavior that was unnoticed due to limited monitoring, or if these flares were triggered by the recent close passage of the mysterious, dusty object "G2".
  • Reminder: The Deadline for Swift Cycle 12 proposals is Now Closed (28 Sep 2015)
  • Chandra CALDB 4.6.9 installed at the HEASARC (27 Sep 2015)
    CalDB 4.6.9 is now installed and available at the HEASARC. Chandra 4.6.8 was released on September 23, 2015. Note that this release requires CIAO 4.3 or higher...
