ʻImiloa opened to the public in February, 2006. It is part of the University of Hawaii at Hilo, and is located near the base facilities for several of the Maunakea observatories in University Park for Science and Technology on the UH-H campus, overlooking Hilo Bay. Its unique architectural design includes three large titanium-clad cones, representing the volcanoes Mauna Kea, Mauna Loa and Hualālai. The extensive gardens feature native, endemic and canoe plants brought by the Polynesians. Exhibit halls, planetarium, gift shop, and Sky Garden café are open to the public Tuesday through Sunday. An evening Maunakea Skies star talk is held in the planetarium on the last Saturday of each month.
