Crystal clear night sky above Mauna kea Observatory, on the Big Island of Hawaii.

One of the world’s best spots for astronomical observations, it is also the most sacred land for the native nation. At 4205m (13800ft) it is the highest point on the entire Pacific Ocean.

In fact the dormant volcano is 10,200 meters tall when measured from base (in the ocean) to peak! While the peak is a popular destination for tourists sunrise to sunset, it is closed to visitors at night due to safety (high altitude hazards) and the disturbance of car lights on the telescopes.

The stargazing fans and astro-tourists enjoy the night from the more temperate altitude of the visitor center at 3000m (9000ft). In fact we see more stars from this level compared to the peak due to increased oxygen level!
