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.

Try ROSAT 3c273 1d to get ROSAT data within one degree of 3C273 or chanmaster bii>80 status='archived' to get archived Chandra observation data near the north galactic pole.

Note: For more than one target or when using any qualifier other than a mission, use quotes around targets that have embedded white space.(e.g., 'ar lac').

Latest News
  • Viewing tool updated (23 Mar 2017)
    Swift's orbital pole constraints have been updated in the Viewing tool. The revised coefficients extrapolate the trend for the next year.
  • NICER expected launch date: May 14, 2017 (21 March 2017)
    NICER is currently scheduled for launch to the ISS on May 14, 2017 from the Kennedy Space Center.
  • NASA's Swift Mission Maps a Star's 'Death Spiral' into a Black Hole (21 Mar 2017)
    Some 290 Myrs ago, a star much like the sun wandered too close to the central black hole of its galaxy. Intense tides tore the star apart, which produced an eruption of optical, UV and X-ray light that first reached Earth in 2014. Now, a team of scientists using observations from Swift have mapped out how and where these different wavelengths were produced in the event, named ASASSN-14li, as the shattered star's debris circled the black hole: see Pasham et al. (2017, ApJ837, L30) for the full details.
  • 15th INTEGRAL Announcement of Opportunity (21 Mar 2017)
    The ESA Director of Science and Robotic Exploration (Prof. Alvaro Giménez Cañete) has released the 15th Announcement of Opportunity for observing proposals with INTEGRAL. The deadline for proposal submission is March 31, 2017. Additional information can be found on the ESA INTEGRAL website.
  • Chandra Deep Field-South 7-Megasecond X-Ray Source Catalog (16 Mar 2017)
    This catalog of 1,055 X-ray sources detected in the combination of 102 separate observations of the CDF-S field (for a total cleaned exposure time of 6.73 Ms) by Chandra's Advanced CCD Imaging Spectrometer imaging array (ACIS-I) from Luo et al. 2017, ApJS, 228, 2 is now available in Browse and Xamin.
  • SkyView V3.2.3 Beware the Ides of March! (15 Mar 2017)
    Over the next few days (as early as noon 3/15) the SkyView servers will be transitioning to requiring secure HTTP, i.e., HTTPS, URLs to access SkyView services.  This is part of a mandated transition of all NASA (and indeed all … Continue reading
