Transit of Venus 2012—Sun Show Will Be Last for a Century

The Joys of the Universe in Action “After the 2012 Venus transit, we won’t see another until 2117…[the] transit of Venus will be visible even to the naked eye—although astronomers caution that people should never look directly at the sun without proper protection.

To watch safely, observers should always use special “eclipse glasses” or telescopes equipped with solar filters. Perhaps the safest way to watch the transit of Venus is to make a pinhole camera.”  

Venus glides across the sun’s face during its previous transit, seen from Flagler Beach Pier in Florida.
