The Veritasium treatment of the final transit of Venus this century. The weather behaved for some key moments allowing me to observe Venus passing across the disk of the sun. The transit of Venus is steeped in historical significance. Observations of the transit in 1769 led to the first really accurate calculation of the Earth-Sun distance (or one astronomical unit AU). Since Cook was in Tahiti he then mapped the East coast of Australia and parts of New Zealand.
