1769 Transit of Venus observed from Tahiti search for the alleged southern continent. HMS Bark "Endeavour" was chosen to take the astronomers and other scientists to Tahiti. James Cook was commissioned as Lieutenant and appointed to command the vessel. Cook was the obvious choice as he was an outstanding seaman with navigational qualifications, a capable astronomer and had observed a 1766 annular eclipse in Newfoundland that was communicated to the Royal Society by John Bevis. Once the "Endeavour" arrived on the island, Cook decided to set up the Venus transit observatory on shore. He required a completely stable platform which the ship could not provide and plenty
1769 Transit of Venus observed from Tahiti measuring the apparent solar parallax between different points on the surface of the Earth. In a 1716 issue of the "Philosophical Transactions of the Royal Society", Edmund Halley illustrated Gregory's theory more fully and explained further how it could establish the distance between the Earth and the Sun. In his report, Halley suggested places that a full transit should be viewed due to a "cone of visibility." Places he recommended for observing the phenomenon included the Hudson Bay, Norway and the Molucca Islands. The next transits would occur in 1761 and 1769. Halley died in 1742, almost twenty years before
