Opened in 2006 as part of the University of Hawai‘i system, the $28 million, 40,000-square-foot complex features hands-on exhibits and a state-of-the-art planetarium that brings the universe — and Hawai‘i’s role in it — to life. Whether you’re tracing the ancient Polynesian art of wayfinding or exploring the latest astronomical discoveries atop Maunakea, ʻImiloa offers a unique, enriching experience for all ages.

The Worldwide Voyage of Hokule’a
The Hōkūleʻa is a double-hulled Hawaiian voyaging canoe built using traditional Polynesian design — and navigated without modern instruments. In 2017, it completed one of the most ambitious cultural journeys of our time: a 47-month, 43,000-nautical-mile voyage around the globe. Using only the stars, wind, waves, and other natural cues, the crew visited 36 countries, nearly 100 Indigenous territories, and 345 ports, spreading a powerful message of sustainability, cultural revival, and global unity.
This historic journey is honored at the ʻImiloa Astronomy Center, where visitors can explore how traditional Hawaiian navigation and science intersect. ʻImiloa stands as a testament to the brilliance of the past and the promise of the future — inviting you to see the universe through both ancient eyes and modern lenses.
What does a Voyaging Canoe have to do with a Planetarium?
The name ‘Imiloa means to “seek far” — discover new knowledge.
Ancient Hawaiians used the stars to guide them long distances in voyaging canoes. They relied on constellations, tides, clouds, birds, winds, and even the smell of the winds to guide them to land. Last year, I brought my grandson to ʻImiloa for the first time. Watching his face light up in that “aha” moment — when he realized the connection between the stars above and the history of the land — was unforgettable.

A State-of-the-Art Planetarium
The ʻImiloa Astronomy Center in Hilo, Hawaiʻi is a state-of-the-art planetarium that offers visitors an immersive journey through the cosmos. The 120-seat theater is equipped with a full-dome digital projection system and 5.1 surround sound, creating a captivating audio-visual experience.
In November 2023, the planetarium underwent a significant $720,000 upgrade funded by NASA. The enhancements included the installation of a 10K-resolution system utilizing ten laser-illuminated projectors, elevating the clarity and vibrancy of the visual presentations. This upgrade made ʻImiloa’s planetarium one of the most advanced in the nation.
The planetarium’s programming encompasses a variety of shows that blend scientific exploration with cultural narratives. A notable presentation is “Maunakea: Between Earth and Sky,” which delves into the significance of Maunakea from both astronomical and indigenous Hawaiian perspectives. Additionally, the “One Sky Project” offers a series of short full-dome films highlighting indigenous astronomy stories from around the world, emphasizing the shared human connection to the night sky.
“The planetarium is incredible. We saw ‘Mauna Kea – Between Earth and Sky’ earlier this year and that was our favorite part of the place.” — Tripadvisor review
Exhibits and Educational Programs
ʻImiloa offers a diverse array of exhibits and programs designed to engage audiences of all ages. The exhibit hall is divided into thematic areas that explore topics such as the origins of the universe, Polynesian navigation techniques, and the latest astronomical research. Additionally, there is a living exhibit that showcases a diverse range of plants representative of native and culturally significant flora in Hawaii. Interactive displays, dual-language signage (Hawaiian and English), and tactile learning stations make it all super engaging. It’s easy to spend two to three hours here just soaking it in.
“Very well done and quite fascinating. There is of course a lot of astronomy but the museum also has geology and ancient navigation exhibits.” — Tripadvisor review
The exhibits are designed for both keiki (children) and adults. There are two main wings:
- “Origins” delves into cosmology and Hawaiian creation stories. Native gardens are part of the attractions, offering a serene and educational experience.
- “Explorations” showcases Polynesian navigation and current space discoveries happening from Maunakea’s telescopes. Polynesian-introduced plants, also known as “canoe plants,” highlight the cultural heritage and ecological importance of the flora brought by ancient Polynesian mariners.
History and Architecture
The Imiloa Astronomy Center of Hawaii was conceived in the early 2000s by George Jacob, the founding director, who identified the need for a place where Hawaiian cultural traditions and astronomical research could be showcased together. The center’s architecture features three large, titanium-clad cones representing Mauna Kea, Mauna Loa, and Hualālai, reflecting the island’s landscape and the significance of these volcanoes. The design also incorporates native and endemic Hawaiian plants, as well as “canoe plants” brought by Polynesians, creating a living connection to Hawaii’s cultural and natural history.
Cultural Integration and Community Engagement
ʻImiloa places a strong emphasis on community involvement and the perpetuation of Hawaiian language and culture. Programs such as “A Hua He Inoa” exemplify this commitment by involving Hawaiian immersion students in the process of naming astronomical discoveries, which include observations of the solar system and beyond. This initiative not only honors traditional naming practices but also integrates Indigenous knowledge into the global scientific discourse, fostering a sense of pride and ownership among local communities.
Mauna Kea Observatory Connection
The Imiloa Astronomy Center of Hawaii has a strong connection to the Mauna Kea Observatory, one of the world’s premier astronomical research sites. Located on the Big Island, Mauna Kea is home to some of the world’s most advanced telescopes, including the Keck Observatory, the Subaru Telescope, and the Mauna Kea Observatory. The Imiloa Astronomy Center of Hawaii works closely with the Mauna Kea Observatory to provide visitors with a deeper understanding of the latest astronomical research and discoveries. The center’s exhibits and programs showcase the significance of Mauna Kea at the intersection of science and Hawaiian culture.
