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.
