THATCHER, Ariz. — EA Discovery Park recently hosted two special tours of the Mt. Graham International Observatory (MGIO), providing local educators and community leaders with a firsthand look at internationally recognized astronomical research in southeastern Arizona.
The tours, held May 28 and June 2, included 11 participants from Gila Valley Leadership Class 20 and 12 educators attending the annual Southeastern Arizona Teachers Academy (SEATA).
The groups were selected because of their impact on the local community. Gila Valley Leadership participants are developing skills and knowledge to strengthen and serve the region, while educators attending SEATA participate in professional development opportunities designed to increase interest in science, technology, engineering, and mathematics among local students.
The tours began at EA Discovery Park, where participants received an introduction to Mt. Graham and the observatory’s telescope facilities before traveling to the Columbine Ranger Station near the summit. After lunch and an opportunity to experience the mountain environment, the groups continued to the observatory for guided tours of all three telescope facilities.
Participants toured the Submillimeter Telescope, which contributed to the Event Horizon Telescope project that produced the first-ever images of black holes. The groups also visited the Vatican Advanced Technology Telescope, known for its innovative spin-cast, honeycombed mirror design and advanced optical imaging capabilities.
The final stop was the Large Binocular Telescope, which features two 8.4-meter mirrors and supports a wide range of astronomical research projects. Observatory staff and operators provided information about current research, telescope technology, and the international partnerships that support scientific work on Mt. Graham.
Following the tours, participants discussed what they learned and how they could share the experience with others. Responses included surprise at the level of scientific research and technology located in southeastern Arizona, appreciation for the observatory’s international partnerships, and recognition of the role higher education and research play in advancing knowledge and innovation.
Public MGIO tours are offered through EA Discovery Park on most Saturdays from May through October. The tours provide visitors with an opportunity to explore the observatory’s telescope facilities and learn about ongoing astronomical research.
