Modern  History  of  Astronomy  in  Hawaii

“The ancient Hawaiians were astronomers” wrote Queen Liliuokalani, Hawaii's last reigning monarch, in 1897 in the introduction to her translation of the “Kumulipo”.

Captain Cook In 1769 Captain Cook sailed to Tahiti to observe the transit of Venus.

This was one of the most important measurements of its time, determining the size of the solar system and thus the universe.

Continuing on his journey, he “discovered” Hawaii.

Thus astronomy brought both the Polynesian settlers and the European discoverers to Hawaii

1874 Venus Transit

King Kalakaua wrote in 1873: It will afford me unfeigned satisfaction if my kingdom can add its quota toward the successful accomplishment of the most important astronomical observation of the present century and assist, however humbly, the enlightened nations of the earth in these costly enterprises…”

In 1881 King Kalakaua looks through the Lick observatory 12” telescope. He enthusiastically expressed a desire to bring such a telescope to Hawaii. In 1884 a 5” refractor was installed in the dome constructed above Pauahi Hall on the Punahou School Campus.

Haleakalā, 1955

The telescope was supposed to use the ocean as a reflector to form an interferometer.

Reber, the Father of Radio Astronomy, was disappointed by the results of this telescope, mainly due to man-made radio interference from Maui and Oahu.

Reber was the first to build on Haleakalā. His telescope structure collapsed under ice and snow in an ice storm in 1957

The Holy Grail: Earth-2 To find an Earth-like planet around a solar-type star, which is close enough, that future generationss might fly there.

We already have made great strides towards this goal. From work done here in Hawaii we know that ~20% of all stars have Earth-like planets in their habitable zone. The closest of these could be just 10 light years away.

Where is it? Hawaii could well be the gateway to the next planets!

Maunakea – A Sacred Mountain

Hawaiian Shrine on the

– True Summit of Maunakea

•  As the highest peak in Hawaii (Polynesia), Maunakea has enormous importance to Native Hawaiians and is among the most sacred sites in the State.

•  The resurgence of native Hawaiian culture in the later 20th century coincided with the development of Maunakea as an astronomy site, leading to significant tension, activism, protests, etc., particularly in the ‘90’s as 8-10 m class telescopes were built.

•  The future of Maunakea astronomy is inextricably linked to Hawaiian culture.
