Our Last Transit of Venus is a film and long-term archiving project about the Transit of Venus 2012. The project is an initiative of Lightcurve Films (http://lightcurvefilms.com) and has been partly supported by EuroPlaNet (http://europlanet-eu.org) and EuroVenus (http://eurovenus.eu)

A Transit of Venus is when planet Venus passes in front of the Sun as seen from the Earth. This happens at intervals of 121.5, 8, 105.5, 8, 121.5, 8, etc. years. Transits of Venus were observed in 1639, 1761 and 1769, 1874 and 1882 and in 2004. After 2012, one will have to wait until 2117 to see another one.

In the late 17th century Edmund Halley proposed that a Transit of Venus observed from different places on the Earth could be used to solve the biggest question in Astronomy at the time, namely determining the size of the Solar System. The events in the 18th and 19th century led to worldwide expeditions to do exactly that.

In 2004, the exercise was repeated by amateur astronomers and students. Scientists used the Transit to learn more about the atmosphere of planet Venus and about how to observe exoplanets transiting their mother stars. In 2012, similar actions will be organised all over the world, in particular the Venus Twilight Experiment.

A final film is in the make at the moment and I am collecting more footage of the aftermath of the event, the science results and people's memories.
