The Pierre Auger Observatory, dedicated to measuring ultra-high energy cosmic rays, has been promoting for more than two decades educational and scientific outreach activities to make its results known in an understandable language to diverse audiences.
Among its most notable efforts, we can mention the creation of a visitor center at the Observatory site in Malargüe, Argentina, the production of brochures, posters, videos, talks, and special actions with the community in the site of the Observatory and beyond.
In addition to joint efforts, collaborators from participating countries carry out local efforts, some of them related to national initiatives in their respective regions, such as the International Cosmic Day, Masterclasses, exhibitions of artworks with the theme of astroparticles, the Night of the Stars, European Researchers' Night, summer schools and initiatives to improve the gender balance in the science community.
In addition, there have been board games based on the dynamics of the observatory's work, online graphic viewers of the different events, talks, workshops, etc.
In recent years, the Pierre Auger Outreach group has focused on presenting actions that directly impact the community in Malarg\"ue.
However, this time, special emphasis will be placed on highlighting the outreach efforts of Pierre Auger collaborators in various countries.
