Thunder Moon over Pisa
Explanation: What's wrong with this picture? If you figure it out, you may then realize where the image was taken . The oddity lies actually in one of the buildings -- it leans. The Leaning Tower of Pisa has been an iconic legend since shortly after its construction began in the year 117 3. Now part of a UNESCO World Heritage Site , folklore holds that Galileo used the leaning tower to dramatically demonstrate the gravitational principle that objects of different mass fall the same . Between the Leaning Tower of Pisa on the right and Pisa Cathedral and the Pisa Baptistery on the left, a full “Thunder” moon was visible last week when the image composite was taken. Using modern analyses , the tower has been successfully stabilized and, barring the unexpected, should hold its present tilt for the next 200 years.
