Yesterday, millions of people the world over (and a handful of astronauts, over the world) looked to the skies to watch Venus inch its way across the face of the Sun for the last time in over a century.
Some pretty spectacular photos have been popping up since the transit began less than a day ago. Here are a few of our favorites (make sure you click for hi-res versions). You can also check out countless beautiful user-submitted images on flickr and SpaceWeather's Realtime Image Gallery.
