High Energy Astrophysics Science Archive
USRA/CRESST scientists working at the NASA High Energy Astrophysics Science Archive Research Center (HEASARC) provide the astrophysical community immediate access to all types of high-energy astrophysics data and object catalogs, such as the Gamma Ray Burst Catalog. Established in November 1990, HEASARC is the primary site for data archiving for high-energy astronomy missions, in the extreme ultraviolet, X-ray, and gamma-ray wavelengths. The site also provides information on HEASARC Software Packages, which were designed for the analysis of scientific astronomical observations and/or viewing astronomical images. In developing its site, HEASARC utilized a single format for compiling data, known as the FITS standard, and took the next step in standard data structures. These measures provided a means for multi-mission analyses. Additionally, the site provides access to scientists' presentations, astronomical image collections from X-ray astronomy and High-Energy Astrophysics schools, as well as information on related workshops and seminars.
Combined infrared image and Gamma-ray image Cygnus X.
The image above is a combination infrared image (obtained by the Midcourse Space Experiment, MSX) and (in pink and white) a Gamma-ray image obtained by the LAT of a massive region of star formation called Cygnus X
. Cygnus X contains dozens of massive stars, along with remnants of exploded stars, a unique nearby region of massive star formation. Credit: NASA/DOE/LAT Collaboration and IPAC/MSX.
This object, known as SXP 1062
, is shown as the bright blue X-ray emitting object on the right side of the image above. X-ray pulsations from this object show that it turns once every 17.7 minutes - a short day for earthlings but extremely long by neutron star standards. Credit: X-ray: NASA/CXC/ESA/XMM-Newton/L.

A particularly massive and bright stellar nursery is the Tarantula Nebula, 30 Doradus. The relative proximity of 30 Doradus
(about 160,000 light years from us) allows astronomers the chance to study in detail the way in which bursts of star formation proceed. The image above is a composite of an infrared image obtained by the Spitzer Space Telescope and an X-ray image (in blue) obtained by the Chandra X-ray Observatory.
