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
The HEASARC is a member of the NASA Astronomical
Virtual Observatories (NAVO) where we work with other NASA archives to
ensure comprehensive and consistent VO access to NASA mission datasets.
Users may now query the HEASARC's catalogs using VO-enabled services and
specialized tools. This page describes
how to get to the HEASARC VO-enabled
services and provides information on other HEASARC VO activities.
- SkyView V3.3.1: Swift UVOT, UltraVista and CFHT HiPS data (17 Oct 2017)

- NASA Missions Catch First Light from a Gravitational-Wave Event (16 Oct 2017)
Shortly after 8:41am EDT on Aug. 17, 2 seconds after LIGO and
VIRGO detected a gravitational wave event, the Fermi Gamma-ray Space
Telescope picked up a pulse of high-energy light from a powerful explosion,
which was immediately reported to astronomers around the globe as a short
gamma-ray burst. The Swift, Hubble, Chandra and Spitzer missions, along
with dozens of ground-based observatories, including the NASA-funded
Pan-STARRS survey, observed over the next few days and weeks the fading glow
of the expanding debris from this blast, now believed to be a "kilonova".
- First Detection of Gravitational waves from a Binary Neutron Star Inspiral on August 17, 2017 at 8:41am EDT (16 Oct 2017)
The LIGO Scientific and Virgo collaborations report the first
joint detection of a gravitational wave signal from a binary neutron star
system, dubbed GW 170817.
The gravitational waves were emitted during the final moments of the
merger of two neutron stars with masses of about 1.6 and 1.1 times the mass of
the sun and located about 130 million light-years away. 1.7 seconds later the
Fermi GBM detected a short gamma-ray burst (GRB 170817A), and follow-up
multi-wavelength observations pinpointed the counterpart object to be a
kilonova (an r-process supernova) in the elliptical galaxy NGC 4993. The
has just appeared in the Phys Rev Letters, v. 119, 161101 (2017).

- XSPEC 12.9.1o,p Patches Released (12 Oct 2017)
Released on October 10, 2017. Release 12.9.1o fixes a multiple-prompting error in certain cases of missing data files, while 12.9.1p fixes some issues in steppar error messaging.
- Scientists Discover One of the Most Luminous Novae Ever (12 Oct 2017)
et al. (2017, MNRAS, in press) have discovered possibly
the most luminous 'new star' ever - a nova in the direction of one
of our closest neighboring galaxies, the Small Magellanic Cloud (SMC).
Using telescopes from South Africa to Australia to South America, as well as
the orbiting Swift observatory, the team reports that the nova SMCN 2016-10a,
which was discovered on 14th October 2016, is the most luminous nova ever
discovered in the SMC, and one of the brightest ever seen in any galaxy.
