Transits of Venus are a very rare celestial event: since the invention of the telescope in 1608, there have been just eight of them. The most recent one, of course, was Tuesday; the next one will be on 11 December 2117. Here in Berkeley, there were a number of amateur astronomers setup public transit viewings with their telescopes.
To see some absolutely stunning images of the transit, I recommend Phil Plait’s Bad Astronomer, and the Astronomy Picture of the Day.
