A mother and her children looks skyward

A mother and her children looks skyward hoping to catch a glimpse of the transit of Venus at Caltech in Pasadena on June 5, 2012 in California. Astronomers worldwide wore safety glasses and trained their telescopes on the skies to watch Venus pass in front of the Sun, a once-in-a-lifetime event that will not be seen for another 105 years, next occuring in 2117.
