By the end of the 19th Century, the relative spacing of the planets was known but the absolute distance between them was not. This scientific mystery spanning centuries was finally solved by accurate measurement of Venus Transits of 1874 and 1882.

Offering un-obstructed views of the Sun from horizon to horizon and superb weather, Hawaii was perfect for astronomers to view Venus Transits in 1874 and 1882. Such observations accurately determined the scale of the Solar System for the first time.

Sky-watching, navigation and the poetry of the cosmos runs deep in Hawaiian culture. Now Hawaiian elementary school students are diving deeply into astronomy’s the history and future through the Venus Transit.

In 1882, scientists determined Earth’s distance from the Sun by measuring the Venus Transit. This process, now applied in NASA orbiting Kepler Mission, discovers new planets by measuring the light-curve of transit across other stars faraway.

Hawaii is a metaphor for Earth’s place in the cosmos. Native Hawaiians have long recognized the sky’s spiritual and intellectual value. Hawaii hosted observers of the Venus Transits of 1874 & 1882; and it warmly supports astrophysicists today.
