It superimposes DSS background images and allows to view the sky in a real life mode as seen from the main ESO sites. It reads FITS images and catalogues in VOTable format. Its main feature is to perform real-time access and graphical display of a large number of observations by showing instrumental footprints and image previews, and to allow their selection and filtering for subsequent retrieval. VirGO gives astronomers the possibility to easily discover and select data from millions of observations in a new visual and intuitive way. It is a plug-in for the popular open source software Stellarium with added capabilities for browsing professional astronomical data. VirGO is the next generation Visual Browser for the ESO Science Archive Facility developed by the VO Systems Department.
