This is a photograph I took of the planet Mercury crossing in front of the sun on Nov. 8, 2006. I've labeled Mercury in a note on the photo.
From wikipedia: "Transits of Mercury can happen in May or November. November transits occur at intervals of 7, 13, or 33 years; May transits only occur at intervals of 13 or 33 years. The last three transits occurred in 1999, 2003 and 2006; the next will occur in 2016."
This was one of the most mind-blowing things I've seen, watching an entire planet drift in front of a star and then being able to photograph it. I hope you enjoy the full-sized picture by clicking on "All Sizes" above the photo!
