Venus is silhouetted as it crosses in front of the sun as it sets behind the Kansas City, Mo. skyline Tuesday, June 5, 2012. From the U.S. to South Korea, people around the world turned their attention to the daytime sky on Tuesday and early Wednesday in Asia to make sure they caught the once-in-a-lifetime sight of the transit of Venus, which won't be seen for another 105 years.
