KM3NeT, the Cubic Kilometre Neutrino Telescope, is one of the most ambitious neutrino observatories ever built, designed to explore the universe from the depths of the Mediterranean Sea. The infrastructure consists of two main sites: ARCA (Astroparticle Research with Cosmics in the Abyss), off the coast of Sicily, dedicated to the search for high-energy astrophysical neutrinos, and ORCA (Oscillations Research with Cosmics in the Abyss), near Toulon in France, which focuses on low-energy neutrinos for studying neutrino oscillations and mass ordering.

Physics in Advent (PiA) is an engaging and educational project that combines the joy of the holiday season with the excitement of scientific discovery. Designed as a "physics advent calendar," it offers 24 fun and simple physics experiments, one for each day from December 1st to 24th. Participants of all ages are invited to explore, hypothesize, and solve challenges, making physics accessible and enjoyable. PiA encourages curiosity, creativity, and critical thinking, fostering a love for science in a festive and interactive way.

The Pierre Auger Observatory, located in the Mendoza province of Argentina, is the largest experiment in the world dedicated to the study of ultra-high-energy cosmic rays.
