The
Transit of Venus across the face of the Sun occurs on June 5th or June 6th, 2012 depending on your location.
This is an extremely rare event, one of the rarest of the predictable astronomical phenomena, and will be the last time you'll have a chance to see this in your lifetimes!
So exactly when and where do you have to be to see it? How do you observe the sun safely during a transit? What's the best way to photograh it? Why is a Transit of Venus so rare? What's the historical significance of a Venus Transit?
All these questions and more are answered in the article I've written:
Transit of Venus Across the Sun, 6th June 2012 - Observing/Imaging Guide
