Virtual observatory (VO) is a collection of interoperating data archives and software tools which utilize the internet to form a scientific research environment in which astronomical research programs can be conducted. In much the same way as a real observatory consists of telescopes, each with a collection of unique astronomical instruments, the VO consists of a collection of data centres each with unique collections of astronomical data, software systems and processing capabilities. The main goal is to allow transparent and distributed access to data available worldwide. This allows scientists to discover, access, analyze, and combine nature and lab data from heterogeneous data collections in a user-friendly manner. The IVOA (International Virtual Observatory Alliance) is a standards body created by the VO projects to develop and agree the vital interoperability standards upon which the VO implementations are constructed. == Examples == * AstroGrid: the UK's Virtual Observatory Service * Euro-VO: the European VO (a partnership of VOs including AstroGrid, the French-VO, ESO, ESA...) * National Virtual Observatory: the USA's VO * Virtual Observatory, India: the India's Virtual Observatory * Iran Virtual Observatory: the Iran's Virtual Observatory * Virtual Solar Terrestrial Observatory: Tetherless World Research Constellation at Rensselaer Polytechnic Institute in conjunction with the High Altitude Observatory of National Center for Atmospheric Research * SPASE: Space Physics Archive Search and Extract * (TELEIOS ): European Union-funded virtual observatory for Earth observation data. Powered by the CWI MonetDB scientific database, it provides access to TerraSAR-X archive of the DLR.〔 〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Virtual observatory」の詳細全文を読む スポンサード リンク
