Transits of Venus (IAU C196) : New Views of the Solar System and Galaxy

On 24 November 1639 in the tiny Lancashire village of Much Hoole, Jeremiah Horrocks made the first observations of a transit of Venus. In the following century the great expeditions to observe the transits of Venus gave us the most colourful stories in astronomy. IAU C196 coincided with the 8 June 2004 transit of Venus, producing the exciting, eclectic mix that can be found in these proceedings: the amazing history of the English North-country astronomers of the seventeenth century; the AU at a precision of 1.4 m; the explanation for the infamous black drop effect; a possible Mayan observation of a transit of Venus in the thirteenth century; the vexed question of leap seconds and time scales; history, distances, parallaxes, the solar system at exquisite precision and future space missions that will revolutionise astronomy.
