More than 30 schools of the E.E.E. Project participated in the International Cosmic Day 2023. During this edition of the event, hundreds of students followed the seminar by Professor Pasquale Blasi, of the Gran Sasso Science Institute, entitled "The universe that the eye does not see: High Energy Cosmic Accelerators", an interesting journey to the origin of cosmic rays.

The day continued with the presentations of the schools focused on the analysis of data from the POLAR detectors, located at the international scientific station of Ny Alesund: the students studied the coincidences between pairs of detectors. On the occasion of the event, students and professors from high schools in Rome and Lazio followed the ICD from the Fermi Hall of Centro Fermi.
