Historic Alignment over Pisa: The Night Mars Met the Longest Blood Moon
On July 27, 2018, the Piazza dei Miracoli lived up to its name with a rare double-celestial event. This date marked the longest total lunar eclipse of the 21st century, with the moon remaining in Earth’s deep shadow for a staggering 103 minutes.
The "Blood Moon" wasn't the only star of the show. Due to a rare coincidence called Mars Opposition, the Red Planet was at its closest point to Earth in 15 years. This made Mars appear as a brilliant, fiery red "star" positioned remarkably close to the eclipsed moon.
The Tower’s Iconic Tilt This rare sky was anchored by the Leaning Tower of Pisa, a structure that has been "failing" beautifully for over 800 years.
Why it leans: The tower sits on an unstable foundation of soft clay, sand, and shells. It began to tilt as early as 1178, when construction reached just the second floor.
The "Curved" Tower: To compensate for the lean, medieval engineers actually built the upper floors with one side taller than the other. This means the tower isn't just leaning—it’s actually slightly curved.
The Current Angle: After major stabilization work in the late 1990s, the tilt was reduced to approximately 3.97 degrees. This was a calculated move: engineers wanted to make it safe for the next 200 years without losing the famous lean that makes it a world wonder.
In this view, 600 years of human architecture meet millions of miles of cosmic history.
