The HEASARC is a multi-mission astronomy archive for the EUV, X-ray, and Gamma ray wave bands. Because EUV, X and Gamma rays cannot reach the Earth's surface it is necessary to place the telescopes and sensors on spacecraft. The HEASARC now holds the data from 25 observatories covering over 30 years of X-ray, extreme-ultraviolet and gamma-ray astronomy. Data and software from many of the older missions were restored by the HEASARC staff. Examples of these archived missions include ASCA, BeppoSAX, Chandra, Compton GRO, HEAO 1, Einstein Observatory (HEAO 2), EUVE, EXOSAT, HETE-2, INTEGRAL, ROSAT, Rossi XTE, Suzaku, Swift, and XMM-Newton.
The Canadian Astronomy Data Centre (CADC) was established in 1986 by the National Research Council of Canada (NRC), through a grant provided by the Canadian Space Agency (CSA), as one of three world-wide distribution centres for astronomical data obtained with the Hubble Space Telescope (HST).

The European VLBI Network (EVN) is an interferometric array of radio telescopes located primarily in Europe and Asia, with additional telescopes in South Africa and Puerto Rico. The EVN performs high-resolution observations of cosmic radio sources at wavelenghts from 92cm to 7mm. The EVN Data Archive contains, among other things, the correlated data from EVN observations plus pipeline output, including the initial calibration tables to apply to the correlated data and preliminary images. In general, the correlated data and some pipeline results are proprietary for one year following distribution to the PI of the final epoch of observations resulting from a proposal after which the data enters the public domain; more details are in the "EVN Data Access Policy" linked via the archive-introduction page.
The Leicester Database and Archive Service (LEDAS) is an easy to use on-line astronomical database and archive access service, dealing mainly with data from high energy astrophysics missions, but also providing full database functionality for over 200 astronomical catalogues from ground-based observations and space missions. The LEDAS also allows access to images, spectra and light curves in graphics, HDS and FITS formats, as well as access to raw and processed event data. LEDAS provides the primary means of access for the UK astronomical community to the ROSAT Public Data Archive, the ASCA Public Data Archive and the Ginga Products Archive by its Archive Network Interface ARNIE.
<<<!!!>>> NVO - National Virtual Observatory is closed now <<<!!! >>> The National Virtual Observatory (NVO) was the predecessor of the VAO. It was a research project aimed at developing the technologies that would be used to build an operational Virtual Observatory. With the NVO era now over, a new organization has been funded in its place, with the explicit goal of creating useful tools for users to take advantage of the groundwork laid by the NVO. To carry on with the NVO's goals, we hereby introduce you to the Virtual Astronomical Observatory

CAD INASAN was established in 1980 as a branch regional center of the Centre de Donnes Stellaire (CDS). Since that time, the CAD has been working to distribute, create and store astronomical data according to the requirements of time, specifics of techniques and requests of the Russian astronomical community. At present, the staff of the CAD is maintaining mirrors of several major astronomical data resources, keeping a record of Russian astronomical data resources, and is working to create new astronomical data resources. Since 2002, we are the important part of the Russian Virtual Observatory project (member of the International Virtual Observatory Alliance - IVOA). The CAD archive is based on astronomical catalogues received from Strasbourg since 1980. Several well known astronomical archives and databases are also stored at INASAN (e.g. VizieR, ADS, INES, VALD). At present CAD coordinates work on the Russian Virtual Observatory (RVO) project

AtomDB is an atomic database useful for X-ray plasma spectral modeling. The current version of AtomDB is primarly used for modeing collisional plasmas, those where hot electrons colliding with astrophysically abundant elements and ions create X-ray emission. However, AtomDB is also useful when modeling absorption by elements and ions or even photoionized plasmas, where X-ray photons (often from a simple power-law source) interacting with elements and ions create complex spectra.

The Square Kilometre Array (SKA) is a radio telescope with around one million square metres of collecting area, designed to study the Universe with unprecedented speed and sensitivity. The SKA is not a single telescope, but a collection of various types of antennas, called an array, to be spread over long distances. The SKA will be used to answer fundamental questions of science and about the laws of nature, such as: how did the Universe, and the stars and galaxies contained in it, form and evolve? Was Einstein’s theory of relativity correct? What is the nature of ‘dark matter’ and ‘dark energy’? What is the origin of cosmic magnetism? Is there life somewhere else in the Universe?
