E QUINDI USCIMMO A RIVEDER LE STELLE Multimedia experience, as part of the temporary exhibition In cime alle Stelle – the universe as seen through art, archaeology and science/Percorso multimediale, all'interno della mostra temporanea In cime alle Stelle –l'universo tra arte, archeologia e scienza, 2007 Forte di Bard, Aosta ENG Housed in the temporary exhibition spaces of Bard Fortress, this multidisciplinary experience accompanies the visitor on an exploration of the relationship between man and the cosmos, from prehistory until today. Combining a popular approach with scientific rigour, the exhibition includes archaeological finds, manuscripts, scientific instruments, works of art and an experimental video area created by Studio Azzurro. The four works presented in the last part of this exhibition are interactive and focus on the observation of the cosmos, following the ideas developed by Albert Einstein, in particular travel through space and time and his theories on relativity. In the first work, two large stone slabs, dating back to around 5000 years ago, are presented under the starry sky of that time. From this celestial vault, created virtually, a beam shines out from a star 5000 light years away, which can then be intercepted and moved by the visitor in order to trace back the distance and time between that star and the Earth. The second work, Il Sole visto dai piedi (The Sun seen from below), involves visitors in considering the space and time which separates the Earth from the Sun – 8 light minutes = 150 million kilometres–and the visual phenomena which are typical of this star –prominences, mass ejections, explosions. The work Ombra di stelle (Star Shadow) reproduces a star cluster which alters according to the movements of the visitors and demonstrates the principle of space-time deformation in the presence of mass. The last work, Le orme delle galassie (Tracing the galaxies), is inspired by the phenomenon which describes the expansion of the Universe. These installations are the result of a detailed dialogue created between astrophysical consultants from the Aosta Valley Astronomical Observatory and Studio Azzurro which, despite the complexity of the subject matter, has produced a fertile convergence between artistic and scientific approaches.
