Bright-Night, the European Night of Researchers in Tuscany, returns on Friday 26 September.

As always, the protagonists of the Night will be researchers who will bring experiments and demonstrations to the streets, with the aim of bringing citizens closer to science and the world of research.

The theme of the University of Siena’s Bright-Night 2025 will be that of ‘taking care’.

The promoters of the event are the Tuscan universities (Universities of Florence, Pisa, Siena, Stranieri di Siena, Scuola Superiore Sant’Anna di Pisa, Scuola Normale Superiore and Scuola IMT Alti Studi Lucca), together with a wide network of research bodies – including the Pisa Area National Research Council (CNR), the National Institute of Nuclear Physics (INFN), the National Institute of Geophysics and Volcanology (INGV), the European Gravitational Observatory (EGO), INAF Astrophysical Observatory of Arcetri – with the support of the Tuscany Region, as part of the Giovanisì project.
