Transit of Venus

The Transit of Venus occurred when the planet Venus passed in front of the sun from the perspective of those observing it. On Earth, the transit occurred in 1769, which was observed from Tahiti by Captain James Cook's crew, an observation which was eventually used to map the skies. It occurred again on 8 June 2004, as observed by Ian Chesterton. (AUDIO: The Transit of Venus)

Other transits occurred in 1388, 1761 and 1882. (AUDIO: The Gates of Hell)
