Captain James Cook was sent to observe the transit of Venus across the sun from the vantage point of Tahiti. The transit of Venus occurs when the planet Venus passes directly between the Earth and the Sun, and its unlit side can be seen as a small black circle moving across the face of the Sun. Cook's ship, the 'Endeavour', departed England, on 25 August 1768 and reached Tahiti in time for his crew and scientists to set up their instrumentation necessary to observe and report on the transit, which occurred on 3 June 1769.
James Cook's first voyage was from 1768 to 1771.
