For more than five decades, Carnegie Science Las Campanas Observatory (LCO) has been a place where cutting-edge knowledge about the universe is generated. However, its contribution is not limited solely to scientific research. Education, outreach, and engagement with communities are an essential part of its identity, driven by the conviction that astronomy becomes even more valuable when it can be shared, understood, and enjoyed by people.
With this purpose, LCO develops a variety of initiatives aimed at bringing science closer to students, teachers, families, and communities across different territories. Through in-person activities, educational resources, digital content, and inclusive projects, it seeks to spark curiosity, encourage critical thinking, and create opportunities for more people to connect with astronomy and with the work carried out under some of the most privileged skies on the planet.
One of its most representative programs is the observatory’s educational visitation program. Each year, students, teachers, and organizations from different regions of the country have the opportunity to tour the facilities, learn about the telescopes, interact with scientific and technical staff, and discover how modern astronomical research is conducted. Following the interruption caused by the pandemic, these visits resumed in 2022 and have once again become a valuable opportunity for connection between the observatory and the community.
Outreach activities also extend beyond the mountaintop. LCO regularly participates in science fairs, astronomy festivals, student congresses, and community events, creating spaces where science meets education, culture, and local communities.
A key initiative in this effort is the LabMóvil Conciencia Astronomía, developed in partnership with the Giant Magellan Telescope. This mobile laboratory brings hands-on and interactive experiences to schools and public spaces throughout the Atacama and Coquimbo regions, bringing astronomy closer to communities that often have limited opportunities to access this type of activity. Through this program, thousands of children, young people, and families have explored scientific concepts through observation, experimentation, and active learning.
Teacher development is another important area of work. Through workshops, training programs, and educational materials, the observatory supports educators interested in incorporating astronomy into their classrooms. One of its most established initiatives is the Online School for Astronomy Education, held twice a year since 2020, bringing together teachers from different regions of Chile and other Spanish-speaking countries and fostering a learning community that transcends borders.
The protection of dark skies also occupies a central place within these efforts. Light pollution is one of the main threats to astronomical observation and to the preservation of northern Chile’s natural night-sky heritage. For this reason, the observatory develops talks, workshops, and educational activities that help people understand its effects and reflect on the importance of preserving this unique resource. Beyond its impact on science, it is an issue with profound environmental, cultural, and territorial implications.
Digital communication complements and expands this work. Through social media, its website, audiovisual materials, and a variety of outreach formats, Las Campanas shares scientific discoveries, astronomical phenomena, stories about the people who work at the observatory, and educational content designed for diverse audiences. These platforms make it possible to reach thousands of people both within and beyond Chile, strengthening the connection between astronomy and society.
At the same time, the observatory maintains close collaborations with media outlets, scientific institutions, universities, cultural centers, and educational organizations, helping to expand the reach of its initiatives and strengthen the presence of science in public discourse.
Inclusion is embedded throughout all of these activities. In recent years, tactile materials for people with visual impairments, easy-to-read resources, and digital accessibility tools have been developed with the goal of enabling more people to participate in and access scientific knowledge on equal terms.
Likewise, Las Campanas regularly welcomes outstanding students from national educational programs and scientific competitions. For many of them, visiting the observatory and experiencing firsthand the work of astronomers, engineers, technicians, and specialized professionals is a transformative opportunity capable of inspiring new interests and strengthening scientific vocations.
Through all of these initiatives, Las Campanas Observatory reaffirms its commitment to science that is open, approachable, and connected to people. Because alongside exploring the universe, it also seeks to inspire those who observe it, contribute to the education of future generations, and share with society the privilege of discovering how the cosmos works.
