Conceived by founding Director George Jacob in 2001, it features exhibits and shows dealing with Hawaiian culture and history, astronomy (particularly at the Mauna Kea Observatories), and the overlap between the two.
Visitors to ʻImiloa will leave with a new understanding of the early Polynesians, who used the stars to find these isolated islands in the middle of the vast Pacific Ocean.
Additional small theaters show a Kumulipo (Hawaiian origins) story, and an astronomy "birth of the universe" 3D presentation, underwritten by the National Astronomical Observatory of Japan (Subaru Telescope).
Exhibit halls, planetarium, gift shop, and Sky Garden café are open to the public Tuesday through Sunday.
In September 2012 the Sagan Planet Walk, until then located only in Ithaca, New York, was extended with a statue representing Alpha Centauri installed at the Imiloa Astronomy Center.
