The SIGN network welcomes the signing of a Memorandum of Understanding between the Free State of Saxony and the Autonomous Region of Sardinia in support of the Einstein Telescope, Europe’s next generation underground gravitational wave observatory. The agreement, signed in Rome on 12 January 2026, marks an important step in strengthening the strategic partnership between Germany and Italy in large scale research infrastructures. The Einstein Telescope is envisioned as a triangular underground facility with 10 kilometer long arms, designed to detect gravitational waves with unprecedented sensitivity. With an estimated investment of around two billion euros for construction alone, the project represents not only a scientific flagship initiative, but also a catalyst for innovation in microelectronics, precision measurement technologies and advanced computing. The Italian coordination of the project is led by the National Institute for Nuclear Physics, INFN. Professor Marco Pallavicini, Vice President of INFN, presented the Einstein Telescope project at the SIGN annual event in 2025 at Villa Vigoni, highlighting its transformative potential for astrophysics and European scientific cooperation. Following the recent intergovernmental summit between Italy and Germany, Professor Pallavicini was interviewed by the German public broadcaster WDR COSMO, where he discussed the new cooperation between Sardinia and Saxony in the field of astrophysics and the broader implications of the Einstein Telescope for European research and technological competitiveness. The MoU between Saxony and Sardinia reinforces the shared commitment of both regions to position Europe at the forefront of gravitational wave science, while deepening bilateral ties in research, innovation and high technology sectors.
