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.
- XSPEC 12.10.1cde Patches Released (11 Apr 2019)
Update (c) adds an optional argument to the PyXspec Fit.error() function to allow for error estimates on response parameters; (d) fixes a bug the rdblur, kdblur, kdblur2, and kerrconv convolution models; and (e) fixes a bug in the mdefine command.
- XAMIN updated (11 Apr 2019)
The HEASARC XAMIN archive interface has been updated to version 6.0a. This release has many changes associated with use of DataLink to extract data products. It has also been updated to minimize the chance of OutOfMemory errors.
- NuSTAR CALDB Update (11 Apr 2019)
The NuSTAR CALibration DataBase was updated on April 11, 2019 (CALDB version 20190410). This updates the NuSTAR clock correction file to version 92, valid through 2019-04-10.
- Swift CALDB Data updated (08 Apr 2019)
The Swift SC clock correction has been updated (CALDB update version 20190405).
- 2019 NHFP/Einstein Postdoctoral Fellows Selected (5 Apr 2019)
NASA has announced the selection of the 2019 NASA Hubble
Fellowship Program (NHFP), which supports postdoctoral fellows
performing research across all of NASA astrophysics. NHFP postdocs are
named as Hubble, Einstein, and Sagan fellows, depending on their
research topics. Awards support each Fellow through a U.S. Host
Institution for up to three years.
Full biographies and other information about this year's Fellows, including each Fellow's research plans, are available

- Planck Catalog of Galactic Cold Clumps (PlanckGCC) Released (5 Apr 2019)
The Planck Catalog of Galactic Cold Clumps (PGCC) is an
all-sky catalog of 13188 Galactic cold clump candidates detected by
Planck. This table is now available in Browse and
