ʻImiloa, which means 'exploring new knowledge,' is a $28 million museum and planetarium complex with a twist: it juxtaposes modern astronomy on Mauna Kea with ancient Polynesian ocean voyaging. Who would've thought that the mythical kumulipo (Hawaiian creation story) and the scientific big bang theory have parallels? It's a great family attraction and the natural complement to a summit tour. One planetarium show is included with admission.
