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.

  • IXPE on the cover of Galaxies (21 Oct 2024)
    IXPE made the cover of the October 2024 edition of Galaxies with a paper on probing magnetic fields in young supernova remnants with IXPE by Pat Slane et al. The work explore how X-ray polarimetry using IXPE provides insights into magnetic field structures and particle acceleration mechanisms in young supernova remnants. This article belongs to a special issue of the journal titled "X-Ray Polarimetry: A New Era Begins with the Imaging X-Ray Polarimetry Explorer"
