400 anni fa: Galileo e il telescopio

Convegno

Ciclo di incontri “Da Galileo alla conquista della Luna”, organizzato dall'Istituto di Istruzione “A. Degasperi” in collaborazione con l'UATV (Unione Astrofili del Tesino e Valsugana) e la Biblioteca Comunale di Borgo Valsugana.

Grazie alla recente invenzione del cannocchiale, Galileo Galilei si dedica con passione all’astronomia e pubblica il 13 marzo 1610 il trattato Sidereus Nuncius (“Annuncio sugli astri”), che rivoluziona le conoscenze del cielo. Viene ricostruita la storia del cannocchiale, strumento non inventato ma perfezionato da Galileo, per la prima volta usato in campo astronomico, e si commentano i suoi rivoluzionari disegni della Luna, delle stelle, di Giove, Venere e Saturno. Le nuove scoperte mettono in crisi il sistema tolemaico e gettano lo scompiglio in un mondo di credenze filosofiche e di visioni cosmologiche vecchie di duemila anni.
