The European Researchers' Night is one of Europe's largest science outreach events. 
The event is held in more than 370 cities on the continent and is funded by the European Commission under the Marie Sklodowska-Curie Actions (MSCA) -an initiative to promote scientific careers in Europe-, which is part of Horizon Europe, the European Union's Framework Programme for Research and Innovation.

The UPV/EHU is organising this initiative in the context of the European project G9- SCIENCE4ALL, promoted by the 9 Group of Universities (G-9): Cantabria, Castilla la Mancha, Extremadura, Illes Balears, Navarra, Oviedo, Basque Country and Zaragoza with the collaboration of the University of La Rioja.

The TSR Lab has participated in the editions of years 2020, 2022 and 2024.
