I'm a big astronomy buff. This is very cool. In the US, I've read, it will only be visible the first two hours after sunrise- you'll literally need to look at the sun to see a dark speck on it, so either use VERY good eye protection or do the pin-hole camera thing.

Next Tuesday, the planet named after the Romans' Goddess of Love -- in reality, a scorched hell where rainfall takes the form of sulphuric acid -- passes between the Earth and the Sun, a sight unseen by anyone alive today.
The so-called Venus transit is in fact an eclipse, but unlike a solar eclipse, the Sun will be hardly dimmed.
Instead, Venus will appear like a little black dot, eerily crawling across the face of our star for some six hours.
If weather permits, the sight, running from 0513-1126 GMT, should be visible to five billion people, but skygazers absolutely must use proper filters to avoid eye damage.
