The Pierre Auger Observatory in Argentina started its construction in 1999 and is operating at full capacity since 2008. From its initiation, scientists and staff of the Observatory are focused on working at the frontiers of scientific knowledge and on serving as a reference on education and outreach. The impact of the interactive new approach on science communication for the general public and the connections with other institutions in the region such as the Planetarium of Malargüe and the University of Cuyo produce great synergy with the community. The year 2019, the year of the centenary of the International Astronomical Union, provides an opportunity to develop new activities in the framework of continuous innovation in education and outreach. In this presentation, we propose a virtual trip through the 20 years that the Auger Observatory transmits scientific knowledge in Malargüe and beyond.
