The Ohana project aims to use seven big telescopes on top of Mauna Kea, Hawaiʻi Big Island, in an interferometer configuration. Mauna Kea is a former volcano whose height is 13,600 ft (4,145 m). It is a good site for telescopes which probe the universe in the optical and infrared wavelengths because of its altitude and low levels of light pollution. OHANA stands for Optical Hawaiian Array for Nanoradian Astronomy. In Hawaiʻian, ‘ohana means "family".
