NASA's Transit of Venus Sun-Earth Day Event!

This year will be the last Transit of Venus to be seen in our lifetime. The next will not occur until 2117. To mark the occasion, NASA will set up a live telecast of the event from Hawaii which is the best place to view it.

During the six hours a number of video clips were contracted to highlight the science behind the Transit and the culture and history of Hawaii.

    I knew what the Transit of Venus was before this movie, and how rare it is, but not that scientists used the Transits for measuring the size of the solar system! What a great explanation!

    The charts from 3:53 to 3:57 and can also be easily noted in 2004 vs 2012 transits, has anyone tried to model the oscillation of our orbits based on that wobble?

    4:00 there is no such thing as "point fifty-nine".  It is "point five nine".

    The photo you have used at 3:08 is actually the photo from Eden, NSW not Hawaii. Great video though.
