New ideas\, new instruments\, new m ethods\, including the open exchange of information and cooperation betwee n scientists even across national borders\, made it possible to make impor tant discoveries about the Solar System – the whole universe as it was t hen known. The process was faster than in the past\, and all this was surr ounded by a general cultural context of great ferment.\nThe conference wil l be accompanied by a series of events aimed at student and general public \, culminating in a day dedicated to observing the sun from Piazza Maggior e in Bologna\, with guided visits to the Great Meridian of San Petronio on 21 June.
