IVOA was formed in June 2002 with a mission to facilitate the international coordination and collaboration necessary for the development and
deployment of the tools, systems and organizational structures necessary to enable the international utilization of astronomical archives as an integrated and
interoperating virtual observatory.
The IVOA comprises 16 VO projects from Armenia, Australia, Canada, China, Europe, France, Germany, Hungary, India, Italy, Japan, Korea, Russia, Spain, the UK and
the US. The work of the IVOA focuses on the development of standards.
The Gemini Observatory – the Gemini South telescope is located in the Chilean Andes and the Gemini North Telescope is located on Hawaii’s Mauna Kea – and the
National Optical Astronomy Observatory (NOAO) produce data products for US optical astronomy science, which are also being incorporated into the IVOA.
