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.
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.

- Swift XRT CALDB updated (12 Aug 2022)
The Swift XRT caldb has been updated to version 20220803 ...
- EFEDSMAIN - eROSITA Main X-ray (0.2 -2.3 keV) Source Catalog Released (5 Aug 2022)
SRG/eROSITA performed scanning observations of the ~140 square degrees eROSITA Final Equatorial Depth Survey (eFEDS) field as part of its performance verification phase. The eROSITA main X-ray source catalog (EFEDSMAIN) presents the primary
catalog of 27,910 X-ray sources, including 542 with significant spatial
extent, detected in the 0.2-2.3 keV energy range. The associated
eROSITA Hard X-ray source catalog (EFEDSHARD) table presents the hard band sample of 246 sources detected in the energy range 2.3-5.0 keV. Both are
now available in both Browse
and Xamin.
- ETACHAMAIN - Eta Chamaeleontis eROSITA EDR Field X-Ray (0.2-2.3
keV) Source Catalog Released (5 Aug 2022)
The nearby young open cluster eta Chamaeleontis was observed by
eROSITA/SRG during its performance verification phase for 150 ks. This table contains the "main" (0.2-2.3 keV) catalog of the X-ray
sources in the eta Chamaeleontis field (ETACHAMAIN), which is released
along with the associated
"hard" (2.3-5.0 keV) catalog (ETACHAHARD). Both are
now available in both Browse
and Xamin.

The NuSTAR FPM caldb has been updated to version 20220802. This release includes a new clock correction file, v143. Please see the release notes for more details.
- 2022 NICER Proposal and Science Workshop, Aug 31-Sep 1 (28 Jul 2022)
In anticipation of the Cycle 5 proposal deadline (Sep 14, 2022). the NICER project will hold a Proposal and Science workshop highlighting the technical and scientific capabilities and strength of the NICER mission. The workshop will be held virtually on August 31st and September 1st, 09:00-11:00 and 14:00-16:00 EDT. Registration is free.
- XMMSTACK- XMM-Newton Serendipitous Source
Catalog from Stacked Observations (4XMM-DR12s) Released (28 Jul 2022)
The stacked catalog (XMMSTACK) and associated observation
data (
XMMSTACKOB) offer new versions of the stacked catalog built
from 9,355 4XMM-DR12 overlapping observations. XMMSTACK contains 1,620
stacks (or groups). The catalog contains 386,043 sources, with each
observation also provided in the associated XMMSTACKOB table. Both are
now available in both Browse
and Xamin.
