The observations of the Transits of Venus in the 18th and 19th centuries sought to determine the dimensions of the solar system. They were international collaborations on an unprecedented scale; collaborations that rose above war and personal conflict. Expeditions were sent all over the world and their data was collected and analysed by the astronomical community.
This website is also a global collaboration. It provides a set of historical instruments and images, drawing on collections around the world. Institutions and individuals are invited to expand the site by contributing their own material.
