Chile boasts some of the finest stargazing conditions in the world, paired with state-of-the-art observational facilities. From radio telescope arrays unraveling the complexities of Titan’s atmosphere to infrared observatories aiding in the landmark identification of neutron star mergers, Chile’s observatories are key players in significant astronomical breakthroughs.
Many world-class research facilities in Chile rely on funding from the United States. This collaborative spirit enhances both nations’ commitment to expanding scientific understanding. Despite widespread American fascination with astronomy, the extent of this partnership often goes unnoticed.
The Astronomy in Chile Educator Ambassadors Program (ACEAP) aims to bridge this gap. Now in its fourth year, ACEAP invites American astronomy educators to Chile, allowing them to witness first-hand the operations of astronomical institutions and how they engage with the public. This initiative, collaborating with entities like the National Science Foundation (NSF) and Associated Universities Inc., strives to enrich local and global communities through scientific discourse.
Participants dive deep into the workings of premier observatories, signing up for the essential role of returning to their communities to share the insights and knowledge acquired during their visit.
Informed Messengers
Through ACEAP, a diverse group of educators transforms into knowledgeable advocates for the scientific alliances between the U.S. and Chile. Annually, nine ambassadors are chosen, fostering a growing network of community-minded individuals. Previous ambassadors remain active, providing essential support to newcomers and sharing valuable resources.
Despite visiting the same destinations each year, ACEAP generates varied experiences based on the unique perspectives of each ambassador group. “Every cohort extracts distinct insights,” reflects Charles Blue, the NRAO’s public information officer and a co-principal investigator for the initiative. “What remains consistent is their collective eagerness to disseminate their experiences widely.”
As the first media liaison for ACEAP back in 2017, I joined fellow ambassadors from varying backgrounds—including educators and astrophotographers—each bringing unique skills and interests. One of the participants was a Chilean teacher dedicated to astronomy education in her K-12 setting, highlighting the diversity of insights shared among ambassadors.
First Steps
The nine-day ACEAP program commenced in Santiago, Chile, on June 18, 2017, with a full schedule that typically ran from early morning until late evening. Our journey involved multiple flights and extended drives to reach not only the observatories but also distinct towns and breathtaking landscapes.
Our itinerary included the Cerro Tololo Inter-American Observatory, the Gemini South Observatory, and ALMA (the Atacama Large Millimeter/submillimeter Array), concluding with visits to the Observatorio Astronómico Andino and Observatorio Cerro Mayu—two facilities catering to an emerging astronomical tourism sector aimed at visitors eager to experience Chile’s magnificent skies.
The view of the Southern Hemisphere’s night sky at OAA introduced many of us to celestial wonders previously unobserved. Iconic sights such as the Omega Centauri globular cluster and Carina Nebula captivated our eyes, while the Southern Cross became a bright mark against the Milky Way’s expanse. These Southern Hemisphere constellations felt unfamiliar, evoking an understanding of how students might feel when encountering new astronomical landscapes.
The Observatorio Cerro Mayu beautifully integrates local culture alongside its stunning sky views, with outdoor sculptures representing both astronomical and cultural dimensions central to Chileans’ relationship with the heavens. Under the darker skies at Cerro Mayu, ambassadors enthusiastically engaged in astrophotography during the tranquil nights.
World-Class Observatories
At CTIO, we spent sleepless nights beneath a blanket of stars, combining educational tours with practical nocturnal observations. ACEAP encourages ambassadors to document their experiences through various mediums, allowing them to communicate both their personal experiences and the broader significance of astronomy.
During our explorations, we engaged intimately with significant telescopes, such as the 4m Víctor M. Blanco Telescope and the Yale 1m telescope, both integral to vital research projects. Notably, the 4m telescope contributed to observing the optical afterglow of a monumental neutron star merger in August 2017.
We also ventured to Cerro Pachón, home to the impressive 8.1m Gemini South Telescope and the Southern Astrophysical Research Telescope. Observing the operation of the telescopes, as the operators smoothly transitioned the instruments, was a remarkable sight.
In the heart of the Atacama Desert, ACEAP connected with local schools, offering demonstrations related to safe solar viewing and infrared light. Interacting with students, especially in anticipation of the July 2, 2019, solar eclipse, strengthened outreach efforts initiated by previous ambassadors.
At ALMA, located at 9,500 feet, we engaged with staff and explored the Operations Support Facility, gaining insights into the technology behind this remarkable array. A highlight was our visit to the Array Operations Site (AOS), located at a staggering 16,500 feet. The ultra-clear skies and the extreme environment showcased the advanced engineering required for millimeter and submillimeter observations.
Astronomical Community
ACEAP ambassadors not only navigated the intricacies of observatories but also engaged with wider community efforts to promote STEM. Throughout our journey, we participated in various presentations about the operational nuances of the observatories and discussed public outreach programs in Chile.
This outreach is vital for creating connections between astronomers and the public. The commitment to educational initiatives is evident in the longstanding efforts at CTIO, with remarkable outreach achievements over the decades. Ambassador Rich Lohman uncovered the multifaceted value of investing in astronomy, highlighting humanity’s relentless pursuit of profound questions about our existence and the universe.
Engaging with Chilean culture also formed a meaningful aspect of our journey. From visits to the house of Pablo Neruda in Santiago to experiencing the unique landscapes of the Atacama Desert, we immersed ourselves in a variety of environments that deepen our connection to the region.
A Continuing Journey
In today’s world of instantaneous information exchange, public engagement with scientific advancements has never been more accessible, accentuating the crucial role educators play in inspiring future generations.
ACEAP’s engagements extend beyond the Chilean journey itself, requiring ambassadors to conduct outreach projects that synthesize their Chilean experiences. Discussing plans on the final day of our program, each participant envisioned projects that would reach diverse audiences and extend the global impact of their visit.
These initiatives could range from public lectures to classroom activities that spotlight the critical discoveries made in Chilean observatories. Many ambassadors have embarked on projects that aim to create long-lasting connections between Chilean and American students and educators.
Ambassadors like Jackson have harnessed her experience to create educational tools, while others utilize their newfound knowledge to inspire STEM initiatives in various communities. The collaborative nature of ACEAP has catalyzed friendships and created enduring professional relationships, underscoring the importance of shared endeavors in the pursuit of astronomy.
The initiatives led by ACEAP continue to evolve, made possible by the contributions of the NSF and the unwavering commitment of both American and Chilean scientists and educators. Through programs like ACEAP, we are fostering a vibrant network dedicated to making astronomy approachable and inspiring love for the cosmos and the scientific journey.
Ultimately, ACEAP, like the exploration of Chile’s night sky, is centered around people—testifying to the power of collaboration and shared passion for discovery.
