A 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: UK's Virtual Observatory Service
  • ChiVO: the Chilean Virtual Observatory
  • Euro-VO: the European VO (a partnership of VOs including AstroGrid, the French-VO, ESO, ESA...)
  • National Virtual Observatory: USA's VO
  • The eSTAR Project: a UK-funded virtual observatory project for autonomous ground-based followup to transient events.
  • Virtual Observatory, India: India's Virtual Observatory
  • Iran Virtual Observatory: 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.[1]
